John von Neumann was a Hungarian-American mathematician and physicist who made significant contributions to a number of fields, including mathematics, economics, and computer science. Von Neumann is best known for his work on game theory, which is used in economics to analyze situations in which two or more parties compete.

Von Neumann was born in 1903 in Budapest, Hungary. He attended the University of Budapest, where he studied mathematics and physics. Von Neumann graduated from the university in 1925 with a Ph.D. in mathematics.

Von Neumann made significant contributions to a number of fields, including mathematics, economics, and computer science. In 1928, he published his influential paper “Theory of Parlor Games,” which introduced the concept of game theory. Von Neumann also made important contributions to the fields of quantum mechanics and nuclear physics.

Von Neumann died in 1957 in Washington, D.C., United States. In 1994, he was posthumously awarded the Nobel Prize in Economics.
