History
From high desert mesas to national laboratory

Historical photo from Los Alamos National Laboratory (LANL). On April 20, 1943, the University of California signed a contract with the United States Army Corps of Engineers to operate a secret laboratory in the mountains of northern New Mexico. The university accepted the task of managing Los Alamos as a service to the nation. The Los Alamos Laboratory sprang up overnight.
The beginning of the atomic bomb
Los Alamos’ history goes back well before 1943, but World War II and the arrival of the Manhattan Project in the spring of that year turned what had been a calm and quiet collection of mesas and canyons into an industrial scale laboratory bent on the creation of the first atomic bombs. Los Alamos would go on to become the world leading laboratory in many fields of science that it is today.
History questions to ponder
Shortly after the end of WWII, Robert Oppenheimer left Los Alamos to return to academia. Dr. Norris Bradbury agreed to take on the reins at Los Alamos for six months, and he stayed as Director for 25 years.
Just in the first nine months the count was around 80. Then Project Y families got down to serious creative work.
The Manhattan Project’s first dedicated office was on the 18th floor of a tower at the corner of Broadway and Chambers Street in Manhattan, New York. Army Corps of Engineers practice at the time was to use locations for naming protocols.
