A
John von Neumann was the oldest of three children of a banker,and his speed of learning new ideas and handling problems stood out early.At 17,his father tried to persuade him not to become a mathematician because he might lead a poor life,so Von Neumann agreed to study chemistry as well.In 1926,at 23,he received a degree in chemical engineering and a PhD in mathematics.From then on,mathematics provided well enough for him,and he never had to turn to chemistry.
In 1930,Von Neumann visited Princeton University for a year and then became a professor there.His first book was published in 1932.In 1933,the Institute for Advanced Study was formed,and he became one of the six full-time people (Einstein was one of the others).
World War Ⅱ hugely changed Von Neumann’s areas of interest.Until 1940 he had been a great pure mathematician.During and after the war, he became one of the best mathematicians who put mathematics theories into practice.During the last part of the war he became interested in computing machines.After the war,Von Neumann continued his work with computers, and was generally very active in government service.He received many awards,was the president of the American Mathematical Society and was a member of the Atomic Energy Commission.He died in 1957 of cancer.
