While on a walk, Albert and Roberta ran into Abe Girschick, Olaf Helmer and Chen McKinsey on the street in Santa Monica. Albert knew the three from his days as a student and in government service. The three mathematicians "... were overjoyed to see us. Mathematical logic was a very, very small world. There were only a little over a dozen mathematical logicians before the war in the United States ..." Girschick, Helmer and McKinsey were working at the recently formed RAND Corporation. With their help, Hans Speier, the head of the RAND social science division, hired Roberta, initially to write book abstracts for circulation to the RAND staff. When General Panel Corporation finally went out of business in 1951, Albert wanted to return to academia in the east, but Roberta was intent on remaining in California. She set up a meeting between Albert and Charles J. Hitch, the head of the RAND economics department. The two hit it off and Wohlstetter was brought on as a consultant to the Mathematics Department.
