**John von Neumann**He was born on December 28, 1903. He was a Hungarian-American mathematician who made important contributions in a wide range of fields.

The eldest of three brothers, **von Neumann** He was born with the name Neumann Janos Lajos. His ancestors had originally emigrated to Hungary from Russia. **John** He was a child prodigy who showed a great aptitude for languages, memorization and mathematics. By the age of six, he could exchange jokes in ancient Greek, memorize phone books, and display prodigious mental arithmetic skills. He received his Ph.D. in mathematics from the Pázmány Peter University in Budapest at the age of 22. At the same time, he obtained his diploma in chemical engineering from ETH Zurich in Switzerland. **John neumann** married twice. First with Mariette Kövesi in 1930, just before emigrating to the United States. They had a daughter. He then divorced her in 1937, and married Klari Dan in 1938.

In 1937, he became a naturalized citizen of the United States. In 1938, **von Neumann** He was awarded the Bôcher Memorial Prize for his work in analysis.

**Von Neumann **He also created the field of cellular automata without the help of computers, building the first self-replicating automata with pencil and graph paper. Throughout his life, **von Neumann **he had the respect and admiration of business and government leaders, something his fellow scientists often belittled.

His interest in weather forecasting led him to manipulate the environment by diffusing dyes in the polar caps to improve the absorption of solar radiation, which increases global temperature.

The main contribution of **Von Neumann** To the atomic bomb was the concept and design of the explosive lenses needed to compress the plutonium core of the Trinity test device. The work of the hydrogen bomb **Von Neumann** it also developed in the field of computer science, where he and Stanislaw Ulam developed simulations on von Neumann’s digital computers for hydrodynamic calculations. During this time, he contributed to the development of the Monte Carlo method, which made it possible to approximate complicated problems using random numbers.

The first significant contribution of **Von Neumann** to economics was the Minimax theorem of 1928. This theorem states that in certain zero-sum games with perfect information, there is a strategy for each player that allows both players to minimize their maximum losses.

An amazingly creative mathematician, **John von Neumann** it has played a fairly important role in postwar economic theory.

**John von Neumann** died on February 8, 1957 (age 53) in Washington, DC, United States.
