Thanks to Peggy Kidwell (below) we have a confirmed sighting of "stored program" in the wild in 1949. In fact two, in internal IBM documents. This is very suggestive when taken in conjunction with something I noticed in searching the ACM DL yesterday, which is that 6 of the 11 uses it located through the end of 1960 were in papers written by IBM staff. So, an attractive hypothesis is that the term was coined within IBM Poughkeepsie in 1949 during early work on IBM's first experimental stored program computer, the Test Assembly. As the 604 calculator being cannibalized for its electronic arithmetic unit already had a plugboard programming mechanism it makes sense that the team would want a clear name for the separate capability they were building to execute a program stored in Williams Tubes backed by a drum.

See, for example, Nathaniel Rochester, "Plans for the Data Processing Test Assembly," Document 05.14.24. See also H. A. Mussell & C. E. Frizzell, "Stored Program," December 27, 1949, which refers to Rochester's paper. This had internal code 05.015.37. The reference is to programs stored on the drum of the machine or electrostatically, as opposed to on a plugboard.

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.
