UNIVAC made its last run at Lawrence Livermore National Laboratory in December 1959. By then, the Laboratory had acquired more powerful IBM computers, capable of 15,000 additions per second. The last Univac run was done by Jonnie Daw, seated. Standing left to right are Stan Helmeci, Ed Lafranchi, Cedric Eastburn, Marv Lehman, Sid Fernbach, Pierre Noyes, and John Hudson. Fernbach was head of computing at Livermore, and a pioneer in developing and applying high-performance computers to solve large scientific problems. No photographer credited, dated December 1959.
