Tom Two bounds for your search. "Stored Program" is not in the 1950 IRE Standard on Computer Terms: Standards on Electronic Computers: Definitions ofTerms, 1950 Proceedings of the IRE Volume: 39 , Issue: 3 Digital Object Identifier: 10.1109/JRPROC.1951.231840 Publication Year: 1951 , Page(s): 271 - 277 BUT IT IS USED IN THE 1953 IRE ARTICLE ON PROGRAMMING. Fundamentals of Digital Computer Programming Thomas, W.H. Proceedings of the IRE Volume: 41 , Issue: 10 Digital Object Identifier: 10.1109/JRPROC.1953.274275 Publication Year: 1953 , Page(s): 1245 - 1249 I SHOULD NOTE THAT IT IS NOT USED IN THE COMPANION 1953 ARTICLE ON THE IBM 701.

Hello everyone,
I have a query related to a project I am working on concerning the conversion of ENIAC to stored program control in 1948, initially to run the first computerized Monte Carlo calculations. All this took place prior to the first operation of the Manchester Baby. That makes the question of what one means by "stored program" a very interesting one.
This question was much discussed in the early days of the history of computing (1970s, early 1980s). I am starting to dig back into primary sources for early use of the phrases "stored program" and "stored program concept" to get a better idea of how these terms were used in the 1940s/early 1950s and what people thought they meant at the time.
To clarify, almost everyone who has written about this cites the 1945 "First Draft of a Report on the EDVAC" as the initial dissemination of the stored program concept although there has been considerable debate as to the source of the ideas contained therein. However that document does not contain the phase "stored program." Or indeed use the word "program" in the body of the text. Or, remarkably, "EDVAC." "Stored" shows up a few times, though less frequently than "remembered." So, ignoring for the moment the relationship of the report to later definitions of the concept, we can agree that it was not the source of the phrase. The most obvious summary of the idea using the report's own terminology would be "remembered instruction device" rather than "stored program computer."
I had thought about the 1946 Moore School lectures as a possible vector for the phase "stored program" as well as the concept. The phrase shows up many times in the Moore School lectures book but so far I have spotted it only in the 1980s editorial material rather than in the original lecture summaries.
By 1954 "stored program computer" is showing up without explanation or citation required in the description of the IBM 650 published in the inaugural issue of Journal of the ACM. It is not particularly common in the ACM DL material for the rest of the decade ("automatic computer" and "digital computer" are more prevalent) but continues to pop up occasionally. The best the OED can do is 1957, which is even later.
So, any thoughts on who came up with this phrase and when? I'm planning to dig deeper in search of early usage, for example into the 1950 "High-Speed Computing Devices" ERA book and some of the other CBI reprints from the 1940s, but it occurred to me that someone on the list might already know the answer to the question.
