In March 1946 John von Neumann attempted to set up an electronic stored-program computer project at the Institute for Advanced Study (IAS) at Princeton. He tried to hire Pres Eckert, but Eckert refused the job, preferring to go into the computer business with John Mauchly as the Electronic Control Company.
In June 1946 engineer Julian Bigelow, who previously had collaborated with Norbert Wiener at MIT, joined von Neumann and Herman Goldstine at the Princeton IAS Electronic Computer Project. He was to a large extent responsible for implementing von Neumann's stored-program concepts.
At Princeton in June 1946 Arthur W. Burks, von Neumann, and Goldstine issued their Preliminary Discussion of the Logical Design of an Electronic Computing Instrument, discussing ideas to be incorporated into the stored-program computer at the IAS.
Around June 1947 Julian Bigelow and his team at Princeton redesigned the IAS machine to include error checking and parallel processing, essential features of what became known as the von Neumann architecture.
