David Hawkins'
Manhattan District History:
Development of the Mark II

"I was privileged to have several conversations with University of Colorado Distinguished Professor Emeritus of Philosophy David Hawkins from 1982 until the year preceding his death on 24 February 2002 at age 88. Primarily our discussions centered on aspects and elements of the Manhattan District History. Professor Hawkins' History is constructed primarily from the extensive notes he compiled from verbal reports and briefings that he received from those persons involved in the work at Los Alamos, where Hawkins was resident from spring 1943 though the end of the war. He wrote the "History" during 1946 and 1947.

The History was CLASSIFIED until 1 December 1961 when it was distributed as report LAMS-2532 (Vol I) by Los Alamos Scientific Laboratory of the University of California, and is Volume I of the two-volume Manhattan District History, Project Y, the Los Alamos Project."
