Martin Sherwin: What was the set-up at Los Alamos, in terms of your relationship to the director [J. Robert Oppenheimer] and how you operated?
Louis Hempelmann: I was working directly under him. I started out with my wife as a half-time secretary, and the technician I brought with me from St. Louis, and Kitty worked for me.
Sherwin: What did Kitty do for you?
Hempelmann: Did blood counts.
Sherwin: Was she a good technician?
