Karl Marx 1818-1883 · Germany / England
Karl Marx (1818-1883) was a German economist, philosopher, historian, and political thinker whose ideas have shaped the modern world more than almost any other thinker of his century. He was born in Trier, in what was then the Prussian Rhineland. His family was Jewish — both his grandfathers had been rabbis — but his father had converted to Lutheran Christianity to be allowed to practise law. Marx grew up in a comfortable middle-class home with a good education. He studied law at the University of Bonn and then philosophy at Berlin, where he was deeply influenced by the philosophy of Hegel. He completed his doctorate in 1841. He could not become a university professor because of his radical views, so he turned to journalism. As editor of a Rhineland newspaper, he began writing on political and economic questions. The Prussian authorities soon shut the paper down. In 1843 he married his childhood sweetheart Jenny von Westphalen and moved to Paris, where he met Friedrich Engels in 1844. The two men would remain close friends and intellectual partners for the rest of Marx's life. Engels, whose family owned textile factories, gave Marx direct knowledge of industrial conditions and later supported him financially for many years. In 1848 Marx and Engels published The Communist Manifesto. Revolutions broke out across Europe that same year. Marx was expelled from several countries before settling in London in 1849. He lived there for the rest of his life, working in the British Museum reading room and writing his great book Capital — the first volume of which was published in 1867. He worked in great poverty for much of this period, losing several children to the diseases of poverty and depending heavily on Engels's financial help. He helped found the International Working Men's Association in 1864, which brought together socialists and labour activists from many countries. He died in London in 1883 at the age of sixty-four. Engels edited and published the remaining volumes of Capital after his death. Marx's influence has been enormous and contested. Movements calling themselves Marxist transformed whole societies in the twentieth century, with results both remarkable and, in some cases, catastrophic. His work itself remains a reference point for anyone trying to understand capitalism, class, and modern history.
"The philosophers have only interpreted the world, in various ways; the point, however, is to change it."
Joan Robinson 1903 - 1983 · United Kingdom
Joan Robinson was a British economist. She was one of the most important economists of the 20th century. Many people think she should have won the Nobel Prize in Economics. She never did, almost certainly because she was a woman and because her views were politically uncomfortable. She was born in 1903 in Camberley, Surrey, in southern England. Her birth name was Joan Maurice. She came from an upper-middle-class family. Her father was a soldier and her mother was the daughter of a famous classics professor. Joan studied economics at Cambridge from 1922. The university had only recently begun allowing women to take degree examinations. She married another young economist, Austin Robinson, in 1926. They had two daughters. She became part of the famous group of Cambridge economists around John Maynard Keynes. Keynes was working out his revolutionary new theory of how economies actually work. Joan was one of his closest collaborators. She helped develop his ideas. She also did major original work of her own. Her 1933 book The Economics of Imperfect Competition introduced ideas that became standard in economics. She taught at Cambridge for over 50 years. She was finally promoted to a full professorship in 1965, much later than she should have been. She was sharp, sometimes difficult, and often controversial. She visited China multiple times during the Cultural Revolution and wrote about it more positively than later events would justify. She also visited North Korea and admired aspects of its economy. Some of these political judgements have aged badly. She remained intellectually active until shortly before her death in 1983.
