IBM's SSEC

January 24, 1948

IBM dedicates the SSEC

IBM dedicates the Selective Sequence Electronic Calculator (SSEC). Later the SSEC was put on public display near the company's Manhattan headquarters so passers-by could watch its operational speed. Before its decommissioning in 1952, the SSEC produced the moon-position tables used for plotting the course of the 1969 Apollo flight to the moon.
