Maria Montessori 1870-1952 · Italy
Maria Montessori (1870-1952) was an Italian educator and doctor whose method of teaching young children has spread to thousands of schools around the world. She was born in Chiaravalle, in central Italy, to a middle-class family. Her father worked for the government; her mother was well-read and encouraged Maria's ambitions. At that time, few women in Italy went to university. Maria wanted to study medicine, which was almost impossible for a woman. She faced strong opposition but did not give up. She entered the University of Rome in 1890 and became one of the first women in Italy to earn a medical degree, graduating in 1896. Her early work as a doctor focused on children with learning difficulties. She worked at a clinic in Rome where she observed these children closely and developed teaching materials that helped them learn. When many of her students then passed the same state exams as children without special needs, she began to wonder whether her methods might work for all children. In 1907 she opened her first school, the Casa dei Bambini (Children's House), in a poor neighbourhood of Rome. The children were aged between three and seven. The results surprised everyone. Children who had been thought wild or undisciplined became focused, calm, and eager to learn. News of the school spread rapidly. Within a few years, schools using her methods opened across Europe, then in the United States and Asia. She wrote many books, including The Montessori Method (1909) and The Absorbent Mind (1949). She was nominated three times for the Nobel Peace Prize because of her work on education for peace. During the Second World War she was trapped in India for seven years, where she continued teaching and developed her ideas about the education of older children. She died in the Netherlands in 1952 at the age of eighty-one. Her schools now educate more than a million children in more than a hundred countries.

Mariana Mazzucato born 1968 · Italy / United States
Mariana Mazzucato is an economist. She was born in Rome, Italy, in 1968. Her father was a physicist, and when she was a child the family moved to the United States, where her father worked at Princeton University. She grew up mostly in the United States and later returned to Europe. She holds both Italian and American citizenship. Mazzucato studied history and international relations as an undergraduate, then moved into economics for her doctorate. Today she is a professor at University College London, in Britain, where she founded a research centre called the Institute for Innovation and Public Purpose. She became widely known in 2013 with her book 'The Entrepreneurial State'. It argued that governments, not just private companies, are major drivers of new technology. Later books include 'The Value of Everything' (2018), 'Mission Economy' (2021), and 'The Big Con' (2023). Mazzucato is unusual among economists for her direct influence on real policy. She has advised governments and international bodies around the world, including in Britain, Italy, South Africa, and the European Union, and she works with the United Nations and other organisations. She is also a strong communicator who reaches a wide public. As a living, working economist, her ideas are still developing and are actively debated.
