The IAS machine was the first electronic computer built at the Institute for Advanced Study (IAS) in Princeton, New Jersey. It is sometimes called the von Neumann machine, since the paper describing its design was edited by John von Neumann, a mathematics professor at both Princeton University and IAS. The computer was built under his direction, starting in 1946 and finished in 1951.[1]
The general organization is called von Neumann architecture, even though it was both conceived and implemented by others.[2] The computer is in the collection of the Smithsonian National Museum of American History but is not currently on display.[3]
