Carl's ability to "make the rounds" and meet people served him throughout his illustrious career 8. C. Hammer, oral history interview by J.R. Baker Ross, CBI OH 56, p. 12. In recognition of IBM's support, the laboratory was renamed The Thomas J. Watson Astronomical Computing Bureau on 6 February 1945 and was the location of numerous firsts in the computer field. 9. SIAM was incorporated as a nonprofit organization under the laws of the State of Delaware on 30 April 1952. 10. A-2 and A-3 were early UNIVAC languages for doing mathematical problems, and used a three-address coding structure. See: J.E.

The system was used in Germany from 1957 to 1962 when the Fieldata project was cancelled due to a general reorganization of the US Army. 14. C. Hammer and H.

Carl Hammer documented everything. One has only to look at the Carl Hammer Papers, 1950–1990 at CBI (CBI 3) to see how thorough he was. In CBI 56, Carl discusses his Roladex file in which he had 9,000 names, addresses, and telephone numbers. 17. C. Hammer, oral history interview by J.R. Baker Ross, CBI OH 56, p. 30. Carl used this diary to prepare his Notes. 18. D.G.

Interestingly, although this area was new to Hammer, on 18 May 1965, he gave an invited address to the New York Chapter of the IEEE on the "somewhat esoteric subject of Traffic Control." 20. Worth \$234 million in 2004 dollars (http://eh.net/hmitcompare/). For comparison purposes, the Sabre system was fully operational in 1964; two other IBM-based systems, Deltamatic and Panamac were operational in 1965. See D.G. Copeland and J.L. McKenney, "Airline Reservation Systems: Lessons from History," MIS Quarterly, vol. 12, no. 3, 1988, p. 356. 21. According to D.G. Copeland et al. (ref. 18), the United and Eastern reservation systems failed because they lacked experience with the application and the technology; see "Sabre: The Development of Information-Based Competence and Execution of Information-Based Competition," Annals, p. 40; D.G. Copeland and J.L. McKenney, "Airline Reservation Systems: Lessons from History," MIS Quarterly, pp. 356–357 (ref. 20). Hammer also refers to this project as a "fiasco" as being resolved in both (UAL and Univac) parties' favor. See Notes, p. 55. 22. Notes, p. 19. 23. Notes, p. 35. 24. Notes, p. 95. 25. Eugene McCarthy (D-Minn.) challenged incumbent Lyndon Johnson for the 1968 Democratic nomination. When Johnson announced he would not run for reelection, the Democratic party selected Vice President Hubert Humphrey (a former senator from Minnesota). 26. Annals, vol. 4, no. 3, 1982, p. 248. 27.

Indeed, shortly after I attended his seminar at American University, Carl enlisted me to talk to one of the local DPMA chapters on whatever I was working on at the time. This was repeated over the years with new topics. 31. AFIPS was a federation of societies formed to provide a mechanism for US participation in the International Federation of Information Processing Societies. Unlike the constituent societies, which were made up of individual members (who shared a common professional interest), AFIPS was a "society of societies."

In the first issue, in July 1979, Aaron Finerman, Chairman of the AFIPS Publications Committee acknowledges the efforts of the Annals Organizing Committee, the Editorial Board, the AFIPS History of Computing Committee (HOCC) and its present and past chairs, Jean Sammet and William Leubbert. Sammet provided an overview of "General AFIPS History of Computing Activities" on pp. 6–8. 35. Annals, "Notices," vol. 7, no. 4, 1985, p. 362. 36. C.

Carl served as one of the governors of the ICCC and remained active in this movement through his retirement in 1981.
