John Mauchly: Stored Programs long before Von Neumann "helped" | ENIAC - The first general-purpose electronic computer
This web site is devoted to ENIAC — “Electronic Numerical Integrator And Computer”. ENIAC was the first general-purpose electronic computer. It was made at the University of Pennsylvania’s Moore School of Electrical Engineering during World War II under the code name "Project PX". Physics professor John W. Mauchly and electrical engineer J. Presper Eckert led the team. Both were civilian employees whose computer work was funded by the United States Army Ballistics Research Laboratory. This is a collection of the best online information about the ENIAC and the people that created it.

John Mauchly: Stored Programs long before von Neumann “helped”

In 1979, stuff just a few months before he died, John Mauchly had a letter published in DATAMATION.  Examples of his writing are rare, but here he clearly wanted to have his say.  In this short piece he describes how he and Pres Eckert, in the wee hours of 1944, worked out the stored-program architecture of EDVAC, the successor to ENIAC.  Later they told John von Neumann, who published it as his own work, and who never repented for it.

Mauchly also brings up the little-known fact that 25% of the ENIAC’s electronic storage was dedicated to programming.  Perhaps it deserves some consideration as a stored-program computer?  The letter also describes some features of BINAC, an under-appreciated innovation.  This was at the time that Burks and Goldstine were trying to drain as much credit away from Eckert and Mauchly and towards Atanasoff and von Neumann as they possible could.  It turned out to be Mauchly’s last published words.
