 on the dropping of the bomb. When the Los Alamos National Laboratory was first being organised a decision was made by Oppenheimer to not compartmentalize the technical information among different departments. This increased the effectiveness of the technical workers in problem solving, and emphasized the urgency of the project in their minds, now they knew what they were working on. So it fell to Serber to give a series of lectures explaining the basic principles and goals of the project. These lectures were printed and supplied to all incoming scientific staff, and became known as The Los Alamos Primer, LA-1. It was declassified in 1965. (Available at Wikimedia Commons). Serber developed the first good theory of bomb disassembly hydrodynamics.

Serber's wife Charlotte was appointed by Oppenheimer to head the technical library at Los Alamos National where she was the only female section leader at wartime Los Alamos.

Serber was to go on the camera plane for the Nagasaki mission, Big Stink, but it left without him when Major Hopkins ordered him off the plane as he had forgotten his parachute, reportedly after the B-29 had already taxied onto the runway. Since Serber was the only crew member who knew how to operate the high-speed camera, Hopkins had to be instructed by radio from Tinian on its use.
