High Quality Content by WIKIPEDIA articles! The Los Alamos Primer was a printed version of the first five lectures on the principles of nuclear weapons given to new arrivals at the top-secret Los Alamos laboratory during the Manhattan Project. They were originally given by the physicist Robert Serber after being delivered in person on April 5-14, 1943, based on conclusions reached at a conference held in July and September 1942 at the University of California, Berkeley by Robert Oppenheimer. The notes from the lecture which became the Primer were written by Edward Condon.
