British Mission Party, 1945

British Mission Party, Birth of the Atomic Age. The Tube Alloys was a codename of the clandestine research and development program, authorized by the United Kingdom with participation from Canada, aiming to developed atomic weapons for Great Britain's nuclear program during World War II. The Tube Alloys program was the first nuclear weapons project of its type, and was eventually subsumed into the US-led Manhattan Project. The first British scientists to go to Los Alamos were mainly nuclear physicists. They included Otto Frisch, who led the Anglo-American group that first demonstrated the critical mass of uranium-235, and Egon Bretscher (Swiss), who found a niche in the group already thinking about fusion weapons. As the team built up, most of the British scientists were allocated to work on implosion weapon problems and to bomb assembly in general. Implosion was considered before the British arrived at Los Alamos, but James Tuck made a significant contribution with his suggestion of explosive lenses for the achievement of highly symmetrical implosions. During 1944 William Penney was recruited to assist with the explosive side of the program. Eventually six British scientists (Bretscher, Frisch, P. B. Moon, Peierls, Penney, and Placzek) became the heads of joint groups and a seventh, Marley, became head of a section. The social triumph of the collaboration between the British and the Americans on the Manhattan Project was a celebratory party hosted by the British Mission. All aspects of the celebration had a properly British flavor: formal invitations, a footman to announce the arrival of the guests, an entree of steak-and-kidney pie, a dessert of trifle, and the best port for ceremonial toasts to the King, the President, and the Grand Alliance. The party took place at the Fuller Lodge on September 22nd, 1945
