Los Alamos National Laboratory
The contract between the University of California and the Manhattan District of the Corps of Engineers (MED) to operate Project Y, Los Alamos Laboratory, was not signed until April 15, 1943, after the project was already under way. It was the first such contract between them.
Bringing in the University of California in 1943 made recruiting for the work of the Laboratory easier. Underhill, however, insisted on more UC involvement.
A letter of intent was drafted by the Army and signed by Underhill March 3, 1943. The detailed contract required five days to negotiate, from April 15 to April 20, 1943. Underhill succeeded in obtaining the conditions traditional in OSRD contracts. Because the work at Los Alamos had already started, Underhill and the Army gave up the attempt to include an agreement for negotiation with the Army in the contract, and although the main part of the contact was signed on April 20, the negotiation agreement was not added until a year later.
