Description

John von Neumann (Hungarian: Neumann János Lajos, 1903–1957) was a Hungarian-American polymath, excelling in mathematics, physics, computer science, engineering, and more. His wide-ranging expertise made him a pioneer in various fields, including mathematics, physics, economics, computing, and statistics. He made significant contributions to quantum physics, functional analysis, game theory, and digital computing. Von Neumann also played a crucial role during World War II, working on the Manhattan Project and contributing to the development of implosion-type nuclear weapons. His expertise extended beyond wartime efforts, consulting for various organizations and chairing Defense Department committees. He was highly regarded as a defense scientist and nuclear weaponry expert, earning accolades such as the Medal of Freedom and having a crater on the Moon named after him.

Depicts the portrait of János Neumann with the IAS machine behind, surrounded by the inscription.

The IAS machine, constructed at the Institute for Advanced Study (IAS) in Princeton, New Jersey, was the first electronic computer of its kind. Often referred to as the von Neumann machine, it was named after John von Neumann, who oversaw its design and construction. Development began in 1946 under his guidance and was completed in 1951. Although the architecture is known as von Neumann architecture, it was conceived and executed by a team of individuals.
