“From 1940 to 1944 Eckert served as director of the United States Nautical Almanac Office (USNAO) at the Naval Observatory in Washington, D.C., where he set up a computation laboratory similar to the one he had left at Columbia. One of his chief tasks at the USNAO was to develop and compute tables for the American Air Almanac, a navigational tool used by the United States armed forces. Eckert devised punched-card methods of generating the tables and a mechanical method of proofreading, using the comparing device on the punched-card reproducer, that insured the absolute accuracy of the tables. These methods are outlined in Eckert’s paper, which also contains his account of an improved table-printing machine designed by IBM and installed in February 1945” (Hook and Norman, 577).
