A computer architecture in which a single memory store holds both program instructions and data, accessed over a shared bus, described in John von Neumann's 1945 First Draft of a Report on the EDVAC. The source is direct that naming the architecture after von Neumann alone is historically inaccurate: J. Presper Eckert and John Mauchly, both already pioneers on this atlas, had essentially finished designing a stored-program computer before discussing the ideas with von Neumann, and the Draft circulated under his name only because Herman Goldstine distributed it before it was finished, to Eckert and Mauchly's documented frustration.

Facts
Disputed
Core Principle
A single memory holding both instructions and data, rather than separate stores for each, is the defining trait; the naming of the principle after von Neumann alone, rather than the EDVAC team that actually worked it out, is itself a standing historiographic dispute. 1
Historian Jack Copeland has called it historically inappropriate to refer to electronic stored-program digital computers as von Neumann machines.

J. Presper Eckert, Pioneers

Why this is disputed. Eckert and Mauchly had essentially finished designing a stored-program computer before discussing the ideas with von Neumann; the architecture's naming credits him alone despite this.

John Mauchly, Pioneers

Why this is disputed. Eckert and Mauchly had essentially finished designing a stored-program computer before discussing the ideas with von Neumann; the architecture's naming credits him alone despite this.
