Introduction

Before the sewing machine, every piece of clothing in the world was made by hand. A man's shirt took about 14 hours of careful stitching. A woman's dress could take many days. Most clothes were made at home, by women, or by hired seamstresses who worked long hours for low pay. Then, between the 1790s and the 1850s, a series of inventors in Europe and the United States built machines that could sew. The early ones did not work well. Then, in 1851, an American named Isaac Singer made a machine that worked, and a company that sold it cleverly. The Singer machine could sew a man's shirt in about one hour — fourteen times faster than by hand. Singer also did something new: he sold the machine on the instalment plan. Working families paid a small amount each week. By 1900, the Singer company had factories in the United States, Scotland, Russia, and elsewhere. Sewing machines were in homes around the world. The machine changed lives in two opposite ways. In homes, it gave women time. Mothers who once spent every spare hour sewing could now do other things. Many women started small businesses making clothes from home. The machine became a symbol of women's economic independence. But the same technology also created the modern garment factory. Workers — mostly young women, often migrants — sat in long rows of machines for ten or twelve hours a day, paid by the piece. The factories were sometimes dangerous. In 1911, a fire at the Triangle Shirtwaist Factory in New York killed 146 workers, most of them young immigrant women. In 2013, the collapse of the Rana Plaza building in Bangladesh killed 1,134 garment workers. The sewing machine is still the heart of how the world is clothed. About 60 percent of all clothing today is made in Bangladesh, China, Vietnam, and a few other countries, by workers — mostly women — sitting at sewing machines. The machine that brought freedom to many homes also brought the sweatshop. Both stories are true. Both still matter.

The object

Origin: Several inventors developed sewing machines in Europe and the United States between the 1790s and 1850s. The first commercially successful machines came from the United States in the 1850s — particularly Isaac Singer's company, founded in 1851. The basic technology spread worldwide within a few decades.
Period: The first practical sewing machines were made in the early 1800s. The Singer company started in 1851. By the 1860s, sewing machines were entering middle-class homes. By 1900, they were used worldwide. The basic design has changed remarkably little since.
Made of: Cast iron frame in older machines, steel and aluminium in newer ones. Modern home machines often have plastic outer casings. Always include: a needle, a bobbin (a small spool that holds the lower thread), a presser foot, a feed dog (small teeth that move the cloth), and either a treadle (foot pedal) or an electric motor.
Size: A typical home sewing machine is 35 to 45 cm long, 25 to 35 cm tall, and weighs 5 to 15 kg. Industrial machines used in factories are larger and faster. The basic shape — needle going up and down, cloth moving past — has stayed remarkably similar for 170 years.
Number of objects: Hundreds of millions of sewing machines have been made since 1851. The Singer company alone has sold over 100 million machines. Today, China and Vietnam are major manufacturing centres for new machines. Bangladesh, India, China, and Vietnam are major centres for machines used in clothing production.
Where it is now: Found in homes, tailor shops, and garment factories worldwide. About 60 percent of the world's clothing today is made on industrial sewing machines, much of it in Bangladesh, China, Vietnam, and other manufacturing countries. Older Singer treadle machines are still used in many places where electricity is uncertain.

Discovery sequence

Think about how clothing was made before the sewing machine. Every shirt, every dress, every pair of trousers — every single seam — was sewn by hand, with a needle and thread, one stitch at a time. A skilled seamstress could make perhaps 30 stitches per minute. Modern sewing machines make over 1,000 stitches per minute. The difference is huge. Before the machine, the work of clothing the world was done mostly by women, in homes, often unpaid. A working family had only a few sets of clothes. Mending was constant. New clothes were rare and expensive. Many people owned no more than two or three changes of clothing in a lifetime. Why might a machine that could sew change so much?

Points to consider (for the teacher)

Because clothing is one of the basic human needs, alongside food and shelter. Anything that changes how clothing is made changes daily life everywhere. The sewing machine made clothes much faster and cheaper to produce. This had several big effects. First, ordinary people could afford more clothes. The basic wardrobe expanded. By 1900, even a poor family in Europe or America might own ten or twenty items of clothing instead of two or three. Second, women in homes got time back. The hours once spent on sewing could go to other things — cooking, child care, gardens, paid work, education, rest. Third, a new kind of factory became possible. If one machine could do the work of fourteen hand sewers, then hundreds of machines in one big building could clothe a whole city. The garment factory was born. The sewing machine is one of the clearest examples in history of how a single technology can change daily life on a massive scale. Students should see that the change touched almost everyone, even people who never owned a machine themselves.

Isaac Singer was not the first inventor of the sewing machine. Englishman Thomas Saint patented an early design in 1790 that probably never worked. Frenchman Barthélemy Thimonnier built working machines in 1830 — and was nearly killed when a mob of hand tailors, fearing for their jobs, burned down his factory. American Walter Hunt invented a key piece — the lockstitch using two threads — in 1834, but did not patent it. American Elias Howe patented a working lockstitch machine in 1846 and won the first big patent battle. Isaac Singer came late. He patented his improvements in 1851. His machine was not the first to work, but it was the first to work well. He combined ideas from several earlier inventors — sometimes without giving them credit. Howe sued him and won. The companies eventually agreed to share patents. What made Singer succeed where others did not?

Points to consider (for the teacher)

Several things together. The machine itself was good — it could sew long straight seams reliably. The needle went up and down, not side to side, which was easier to control. The foot treadle freed both hands for guiding the cloth. But Singer's real genius was business. First, he made the machine for the home as well as the factory. Many earlier makers focused only on industrial customers. Second, he sold the machine on the instalment plan — buyers paid a few dollars a week instead of the whole price at once. This made the machine affordable for ordinary families. Third, he built a worldwide sales network — Singer offices and trained salespeople in dozens of countries. Fourth, he kept improving the design. The 1851 machine was different from the 1880 machine, which was different from the 1910 electric model. Singer was not just an inventor; he was the first person to mass-market a complex consumer technology globally. His instalment plan in particular changed how the world buys things — most cars, refrigerators, and other big items are still bought this way. Students should see that 'the inventor' is rarely one person, and that 'the successful inventor' is often the one who solves the business problems, not just the technical ones.

The sewing machine arrived in the home as a gift to women. Mothers who once spent every spare hour mending and making clothes could now do the same work in a fraction of the time. Many women used the machine to start small businesses — making clothes for neighbours, taking in piece work, sewing for shops. The machine became a path to women's economic independence in many places. But the same machine, in factories, created a different life. The first big garment factories opened in New York, London, and other cities in the late 1800s. Workers — mostly young women, often immigrants — sat in long rows. They were paid by the piece, meaning their pay depended on how many garments they finished. The pay was usually low. The hours were long, often twelve or fourteen a day, six days a week. The buildings were sometimes overcrowded and unsafe. On 25 March 1911, fire broke out at the Triangle Shirtwaist Factory in New York City. The factory was on the eighth, ninth, and tenth floors of a building. The doors to the stairs had been locked by the owners to stop workers from taking breaks. 146 workers died — most of them young Italian and Jewish immigrant women, some as young as 14. The youngest were 14 years old. The fire shocked the United States and led to major new laws on factory safety, fire exits, and working hours. Why might one machine bring such different lives?

Points to consider (for the teacher)

Because the same technology can be used in different conditions, with very different results. In a home, with the worker in control, the sewing machine saved time and gave choices. In a factory, with workers under the control of an owner, the sewing machine could speed up exploitation. The technology itself was neutral. The conditions of use were not. The Triangle fire is one of the most important moments in American labour history. After it, workers organised in larger numbers. Laws changed. Factory inspections began. The International Ladies' Garment Workers' Union grew. The fire showed what unregulated factory work could do, and it helped create the modern system of labour regulation in the United States — though many of the protections came only after deaths. Similar struggles happened in Europe and elsewhere. The pattern was repeated, decades later, in countries that became major clothing producers more recently. Students should see that 'progress' is rarely one-directional. The same machine that freed women in some homes trapped women in some factories. Honest history holds both truths.

Today, most clothing in the world is made on sewing machines in factories in Asia. Bangladesh has become the world's second largest clothing exporter, after China. Over 4 million people work in Bangladesh's garment industry, about 80 percent of them women. The industry has been a path out of poverty for many families. Wages are low by international standards but higher than other work available in rural areas. Women have gained income, independence, and a place outside the home that did not exist for their grandmothers. But the conditions have sometimes been very bad. On 24 April 2013, the Rana Plaza building in Dhaka, Bangladesh, collapsed. The building had been showing cracks the day before, but workers were ordered to come in anyway. 1,134 garment workers died — almost all of them young women. Another 2,500 were injured. Rana Plaza was the deadliest factory accident in modern history. The disaster led to major changes. International brands signed safety agreements (the Accord on Fire and Building Safety, and the Alliance for Bangladesh Worker Safety). Thousands of factories were inspected. Many were upgraded. Bangladeshi workers organised and pushed for higher wages — the minimum wage has more than doubled since 2013, though it is still low by global standards. What does this teach us?

Points to consider (for the teacher)

That the story of the sewing machine is not finished. The same patterns from 1911 New York have appeared again, in different countries, in different decades. The same struggles for safety, for fair pay, for organised labour, for honest factory inspections continue. The Rana Plaza disaster is to Bangladesh what the Triangle fire was to New York. Both led to better conditions, but only after great loss. Bangladeshi garment workers themselves have been the main force for change. They have organised. They have struck. They have insisted on being treated as full human beings, not just as cheap hands at sewing machines. The clothing on most people's backs today was made by these workers. The question of who profits and who suffers in the global garment industry is real and unfinished. International brands earn billions. Workers earn a few dollars per day. Consumers in wealthy countries can buy a t-shirt for less than the price of a coffee. The math does not balance. Students should see that the sewing machine is not just an old object in a museum. It is the working tool of millions of people right now. The conditions of its use are still being decided, by workers, owners, governments, brands, and ordinary consumers who choose what to buy. End the discovery here. The story is alive. Each new shirt is part of it.

What this object teaches

The sewing machine is a tool that uses a needle moving up and down through cloth, combined with a second thread carried by a bobbin underneath, to make a strong stitch much faster than by hand. The first practical machines were developed by several inventors in Europe and the United States between the 1790s and the 1850s. Isaac Singer's company, founded in 1851, was the most successful, partly because Singer's machines worked well and partly because he sold them on the instalment plan — small weekly payments that working families could afford. The machine changed home life by giving women back hours of time previously spent sewing by hand. It also created the modern garment factory, where workers — mostly women — sat at machines for long hours under hard conditions. The Triangle Shirtwaist Fire in New York in 1911 killed 146 garment workers and led to major changes in American labour law. The collapse of the Rana Plaza building in Bangladesh in 2013 killed 1,134 garment workers and led to changes in global factory safety standards. Today, about 60 percent of the world's clothing is made on industrial sewing machines in Bangladesh, China, Vietnam, and a few other countries, by an estimated 60 to 80 million workers. The sewing machine is one of the clearest examples in history of how one technology can change daily life — and of how the same machine can mean freedom in one place and hardship in another.

Key words

Lockstitch

The basic stitch made by most sewing machines. Two threads are used — one from above (the needle) and one from below (the bobbin). They lock together inside the cloth. The stitch is strong and does not unravel easily.

Example: The lockstitch was developed by Elias Howe in the 1840s and is still the most common sewing machine stitch today. Most clothes you wear were made with it.

Bobbin

A small spool that holds the lower thread inside the sewing machine. It sits below the cloth and works with the needle thread to make the lockstitch.

Example: Every sewing machine has a bobbin. Loading and threading the bobbin is one of the first things a new sewer learns.

Treadle

A foot pedal that powers older sewing machines. The user rocks it back and forth with the foot, which spins a wheel and drives the needle. Treadle machines do not need electricity.

Example: Singer treadle machines from the early 1900s are still in use in many parts of the world where electricity is uncertain. They are simple, sturdy, and easy to repair.

Instalment plan

A way of selling expensive items where the buyer pays in small regular amounts (usually weekly or monthly) instead of the full price at once. Singer used this method to sell sewing machines from the 1850s onwards.

Example: The instalment plan made the sewing machine — and many other consumer goods like cars and refrigerators since — affordable for working families. It is one of the most important business inventions of the 1800s.

Garment industry

The whole system of making clothes for sale, from designing to cutting to sewing to shipping. Most modern garment work is done in factories with industrial sewing machines.

Example: The global garment industry employs an estimated 60 to 80 million people, about three quarters of them women. Bangladesh, China, and Vietnam are the largest producers.

Triangle Shirtwaist Fire

A factory fire on 25 March 1911 in New York City that killed 146 garment workers, most of them young immigrant women. One of the worst industrial disasters in American history. Led to major changes in factory safety laws.

Example: The fire is now seen as a turning point in American labour history. The building still stands. Memorials are held every 25 March.

Use this in other subjects

History: Build a class timeline of the sewing machine: early inventors (1790s-1840s), Singer's company (1851), worldwide spread (1860s-1900s), Triangle fire (1911), modern garment industry (1980s onwards), Rana Plaza (2013). The story spans over 200 years and covers most of the modern industrial era.
Science: Discuss how the sewing machine works mechanically. The needle goes up and down. As it descends, it carries a thread through the cloth. As it rises, a hook below catches the thread and loops it around a second thread (from the bobbin). The cloth is pushed forward by the feed dog. This is one of the most elegant mechanical inventions of the 1800s. Compare with hand sewing, where one needle and one thread are used.
Citizenship: The Triangle fire and the Rana Plaza collapse both led to laws protecting workers. Discuss why workplace safety laws matter. Are there other examples in your country of disasters leading to better laws? What conditions are workers in your community protected against?
Ethics: Hold a class discussion: 'When you buy a t-shirt for $5, who paid the real cost?' Most modern clothing is cheap because someone — usually a woman in a developing country — earns a low wage to make it. Discuss whether this is fair. What might 'fair' even mean in a global market? Strong answers will see this is a real ongoing question with no easy answer.
Art: Look at the design of an old Singer sewing machine. The black machine with gold decoration was designed to be beautiful as well as useful. It was meant to look at home in a parlour or living room, like a piece of furniture. Discuss how product design has changed over time. Modern sewing machines often look more like office equipment than household art.
Language: The word 'sweatshop' came from English in the late 1800s, when garment factory workers were said to 'sweat' over their machines for long hours. Discuss how the word has spread to other languages and how it is used today. Words sometimes carry the history of struggles in their meanings.

Common misconceptions

Wrong

Isaac Singer invented the sewing machine.

Right

Several inventors over decades contributed key ideas — Thomas Saint, Barthélemy Thimonnier, Walter Hunt, Elias Howe, and others. Singer's machine combined their ideas, sometimes without proper credit. Howe sued Singer and won. Singer's real genius was business — selling the machine to ordinary families on instalment plans.

Why

'One genius invented X' is rarely true in history. Most major inventions are the result of many people building on each other's ideas.

Wrong

The sewing machine freed women from hard work.

Right

For some women in homes, the machine did save time and create new opportunities. For other women — millions of them, in factories then and now — the machine became the tool of long hours, low pay, and sometimes dangerous conditions. Both stories are true.

Why

'Technology equals progress for everyone' is a comforting story but not always an accurate one. The same tool can mean very different things in different conditions.

Wrong

Bangladeshi garment workers are just victims of a bad system.

Right

Bangladeshi garment workers are real people with their own agency. They have organised, struck, pushed for higher wages, and led the change after Rana Plaza. The minimum wage in Bangladesh's garment sector has more than doubled since 2013, mostly because workers fought for it. They are economic agents and political agents, not just victims.

Why

Treating workers in poor countries only as victims removes their humanity and their power. They are the main force for change in their own industry.

Wrong

Sewing machines are old technology that does not matter much today.

Right

Sewing machines are still the working tool of an estimated 60 to 80 million people worldwide, mostly women. About 60 percent of all clothing today is made on them. The technology that started in 1851 is still the foundation of how the world is clothed.

Why

'Old technology' often means 'still being used by most of the world but not by you'. Most of the global economy still runs on inventions from the 1800s — sewing machines, internal combustion engines, electricity grids, telephones, railways.

Teaching this with care

Treat the garment industry honestly. Both the freedom and the exploitation are real. Do not dwell on either side. Be respectful of the workers — past and present, in New York in 1911 and in Dhaka today. Use 'garment worker' rather than 'sweatshop worker'; the second is often a label used by outsiders, while many workers themselves prefer to identify by their job. The Triangle fire is a serious historical event. Mention the death toll honestly (146 dead, mostly young immigrant women) but do not dwell on graphic details. The youngest victims were 14 years old. Many were Jewish and Italian immigrants. Their names and stories are important and have been documented carefully. Direct interested students to the Kheel Center at Cornell, which has the most complete records. The Rana Plaza disaster is more recent and may feel closer to some students, especially those of Bangladeshi or South Asian heritage. Treat it with similar care — honest about the death toll (1,134 workers, mostly young women) without graphic detail. The aftermath is also important; do not present Bangladesh only as a place of disaster. The country has a thriving garment industry, growing labour movement, and increasing safety standards thanks largely to workers' own efforts. If you have students whose families work in garment factories or related industries, give them space to share if they want, but do not put them on the spot. Avoid lazy 'Western consumer guilt' framings. The question 'who pays for cheap clothes' is real, but the answer is not simply 'feel bad about your t-shirts'. Real change comes from policy, organising, regulation, and workers' agency, not just consumer guilt. Be careful not to present the home/factory contrast as 'good women in homes versus bad factories'. Many women preferred factory work — for the income, the social life, the independence — even when conditions were hard. Use the names of the inventors fairly. Singer is famous, but Hunt, Howe, and Thimonnier all deserve mention. Howe especially had a working machine before Singer and won the patent battle. Finally, end on the present. The sewing machine is still working, in homes and factories, all over the world. The story is not finished.

Check what students have understood

Answer each question in one or two sentences. Use what you have learned about the sewing machine.

What did Isaac Singer do that helped his company succeed where earlier sewing machine makers had failed?

Singer combined several inventors' ideas into a machine that worked well, but his real genius was business — he sold the machine to ordinary families on the instalment plan (small weekly payments) and built a worldwide sales network. He also kept improving the design over time.

Marking note: Award full marks for any answer that mentions the instalment plan or the focus on home customers. Strong answers will mention both.
How did the sewing machine change life in homes?

It made sewing much faster, giving women back hours that had been spent on hand sewing. Many women used the time for other things — paid work, education, family, rest. Some women started small clothes-making businesses from home. The machine became a symbol of women's economic independence in many places.

Marking note: Strong answers will mention both the time saved and at least one specific use of that time.
What was the Triangle Shirtwaist Fire, and why is it important?

A factory fire in New York City on 25 March 1911 that killed 146 garment workers, most of them young immigrant women. The doors had been locked by the owners. The fire led to major changes in factory safety laws in the United States — better fire exits, shorter hours, and stronger rules for workplace safety.

Marking note: Award full marks for any answer that gives the basic facts (year, place, death toll) and mentions the legal changes that followed.
What happened at Rana Plaza in 2013, and what changed afterwards?

The Rana Plaza building in Dhaka, Bangladesh, collapsed on 24 April 2013. 1,134 garment workers died, almost all young women. International brands then signed safety agreements, thousands of factories were inspected, and Bangladeshi workers organised for higher wages — the minimum wage has more than doubled since.

Marking note: Strong answers will mention both the disaster itself and the changes that followed. Either part alone earns partial credit.
Why does the sewing machine still matter today?

About 60 percent of the world's clothing is still made on sewing machines, mostly in factories in Bangladesh, China, Vietnam, and a few other Asian countries. An estimated 60 to 80 million people work at sewing machines, about three quarters of them women. The technology from 1851 is still the foundation of how the world is clothed.

Marking note: Award full marks for any answer that recognises the continued importance of the sewing machine in global clothing production.

Discuss together

These questions have no single right answer. Talk in pairs or small groups, then share your ideas with the class.

Isaac Singer's instalment plan let working families buy a machine they could not otherwise afford. What other things in your life do people buy on instalment plans? What are the good and bad sides?

This question connects history to modern life. Students may suggest: cars, houses, phones, large appliances, university tuition. The good side: things become affordable to ordinary people. The bad side: people can take on too much debt, or pay much more in interest than the item is worth. The deeper point is that Singer's invention of the consumer instalment plan in the 1850s is still shaping the world economy. End by noting that this business idea has been at least as important as the sewing machine itself.
The sewing machine freed some women in homes but trapped others in factories. Are there modern technologies that have similar mixed effects?

Push students to think specifically. They may suggest: smartphones (connect us but also distract us), social media (community but also isolation), washing machines (saved hours but raised expectations of cleanliness), cars (freedom of movement but pollution and traffic), automation (some workers freed, others replaced). The deeper point is that 'progress' is rarely simple. The same tool can have very different effects on different people. Strong answers will recognise that judging a technology requires asking who benefits and who pays — questions that the sewing machine raised 170 years ago and that modern technologies still raise.
You can buy a t-shirt for very little money. Most of it was probably made by a woman in Bangladesh, China, or Vietnam. Is this fair?

This is a genuinely hard question. Students may give different answers. Some will say: the workers earn more than they would in farming, the industry has lifted millions out of poverty, the workers themselves want the jobs. Others will say: the wages are still very low compared to what brands earn and what the t-shirts cost, the conditions can be hard, the system depends on poor workers staying poor. Both views have evidence. Strong answers will see that 'fair' is not a simple judgment, and that the people best placed to answer are often the workers themselves — who have organised, struck, and pushed for change. End by noting that this is a real ongoing question that adults disagree about, and that the best way to think about it is to listen to the workers.

Teaching sequence

THE HOOK (5 min)

Without saying anything about the lesson, ask: 'How long does it take to sew a man's shirt by hand?' Take guesses. Then say: 'About 14 hours. By machine, about an hour. The sewing machine is one of the most important inventions of the modern world. We are going to find out about it.'
INTRODUCE THE OBJECT (10 min)

Describe the sewing machine: a tool that uses a needle and a bobbin to make a strong stitch much faster than by hand. The first practical machines came from several inventors between the 1790s and 1850s. Isaac Singer's company, founded in 1851, was the most successful — partly because the machines worked well, partly because Singer sold them on the instalment plan. Pause and ask: 'What might happen when one machine can do the work of fourteen hand sewers?' Listen to answers. They will lead naturally into the ideas of changed homes, new factories, and a transformed clothing world.
THE TWO STORIES (15 min)

On the board, draw two columns: 'In the home' and 'In the factory'. Under 'In the home', list: women got time back, some started small businesses, machine became a symbol of independence. Under 'In the factory', list: long hours, low pay, dangerous conditions, Triangle fire (1911, 146 dead), Rana Plaza (2013, 1,134 dead). Discuss: how can the same machine mean such different things? End by saying: 'The technology was neutral. The conditions of use were not. This is one of the most important lessons in modern history.'
MODERN GARMENT WORK (10 min)

On a map of the world, mark Bangladesh, China, Vietnam, India, and Cambodia — the major clothing producers. Discuss: 60 percent of all clothing today is made in these countries, mostly by women. The minimum wage in Bangladesh's garment sector has more than doubled since 2013 — mostly because the workers themselves organised. The story is alive. Ask: 'Who do students think changes the conditions of garment work? Brands? Governments? Consumers? Workers?' Strong answers will see all four, with the workers themselves as the main force.
CLOSING (5 min)

Ask: 'What does the sewing machine teach us about how technology changes the world?' Take a few honest answers. End by saying: 'It changes everything — but not in one direction. The same machine can free one person and exploit another. The conditions of use matter as much as the technology itself. Most of the clothes you are wearing right now were sewn by someone, somewhere, on a machine very similar to the one Isaac Singer made in 1851. The story is not finished. It is being decided now, by workers, owners, governments, and ordinary people who choose what to buy.'

Classroom materials

How Long Does It Take?

Instructions: In small groups, students estimate how long it takes to make one piece of clothing they are wearing. Discuss: who probably made it? Where? On what kind of machine? How much did the worker probably earn for that piece? Real numbers: a t-shirt typically takes 5 to 15 minutes to sew in a factory; the worker might earn 10 to 30 cents for it. Discuss what this means about the price you pay for the shirt.

Example: In Mr Hassan's class, students estimated that a $5 t-shirt probably involved about 10 minutes of sewing labour, paying perhaps 20 cents to the worker. The teacher said: 'You have just done some of the basic math of the global garment industry. The numbers raise real questions about who profits and who pays. Adults disagree about what to do about it. The first step is to know the numbers.'

The Inventors

Instructions: Five students each take the role of one inventor: Thomas Saint (England, 1790), Barthélemy Thimonnier (France, 1830), Walter Hunt (United States, 1834), Elias Howe (United States, 1846), Isaac Singer (United States, 1851). Each describes their contribution in one minute. Discuss: was there one inventor of the sewing machine? Strong answers will see that 'invention' is usually a chain of people building on each other's ideas.

Example: In Mrs Diop's class, the role play showed how Singer combined ideas from earlier inventors and was sued by Howe — and lost. The teacher said: 'Most major inventions are like this. The famous name is usually the one who solved the business problem, not necessarily the one who solved the technical problem first. Singer is in the textbooks because he sold the machine to the world.'

Then and Now

Instructions: In small groups, students discuss the parallels between the Triangle Shirtwaist Fire (1911) and the Rana Plaza collapse (2013). Both involved garment factories. Both killed mostly young women workers. Both led to changes in safety laws. What is similar? What is different? Each group shares one parallel they find striking.

Example: In one class, students noticed that both disasters involved building safety problems that had been ignored. The teacher said: 'The patterns repeat. New York 1911 and Dhaka 2013 are 102 years apart and 12,500 kilometres apart, but the basic story is similar. Each disaster led to better laws, but only after deaths. This is one of the hard lessons of industrial history. The hope is that the next change can happen without another disaster.'

Where to go next

Try a lesson on the shipping container for another invention that transformed global trade — the t-shirt that arrived at your door probably travelled in one.
Try a lesson on cotton or another textile-related object to explore the wider story of how the world is clothed.
Try a lesson on barbed wire for another simple invention with massive global effects.
Connect this lesson to history class with a longer project on the Industrial Revolution. The sewing machine is one of the clearest examples of how technology, business, and labour interact.
Connect this lesson to citizenship class with a longer discussion of workplace safety and worker rights. The patterns from 1911 New York are still relevant today.
Connect this lesson to ethics class with a longer discussion of fair trade, ethical consumption, and global supply chains. The questions are real and unfinished.

Key takeaways

The sewing machine is a tool that uses a needle and a bobbin to make a strong stitch much faster than by hand. It can sew a man's shirt in about one hour; by hand the same shirt would take 14 hours.
Several inventors between the 1790s and 1850s contributed key ideas. Isaac Singer's company, founded in 1851, was the most successful — partly because the machines worked well, partly because Singer invented the instalment plan that let ordinary families buy them.
The machine changed home life by giving women back hours of time previously spent on hand sewing. Many used the time for other things — paid work, education, family, rest. Some started small clothes-making businesses.
The same machine also created the modern garment factory. Workers, mostly women, sat in long rows for long hours. The Triangle Shirtwaist Fire of 1911 killed 146 garment workers in New York and led to major changes in American labour law.
Today, about 60 percent of the world's clothing is made on industrial sewing machines, mostly in Bangladesh, China, and Vietnam. The Rana Plaza collapse in Bangladesh in 2013 killed 1,134 garment workers and led to international agreements on factory safety.
Bangladeshi garment workers themselves have been the main force for change since Rana Plaza. The minimum wage in their sector has more than doubled since 2013, largely because they organised and pushed for it. They are economic agents, not just victims.
