John von Neumann was the oldest of 3 children of a

banker，and his speed of learning new ideas and of solving

problems stood out early.At 17，his father tried to

persuade him not to become a mathematician because he may

lead a poor life being a mathematician，and so von Neumann

agreed to study chemistry as well.In 1926，at 23，he

received a degree in chemical engineering and a Ph.D.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 6 full­time people(Einstein was one of the others)in the Sch ool of Mathematics.

He received many awards，was president of the American Mathematical Society and was a member of the Atomic Energy Commission.He died in 1957 of cancer.
