Description: 

"Photograph shows the 60 inch cyclotron at the University of California's Lawrence Radiation Laboratory, Berkeley, soon after its completion in mid-1939. In the photograph are key figures in the development and use of the machine: standing, left to right; Dr. Donald Cooksey, now associate director, emeritus; Dr. Dale Corson, physicist, co-discoverer of element 85; the late Dr. Ernest O. Lawrence, inventor of the cyclotron, Nobel Laureate, and founder of the Laboratory; Dr. Robert Thornton, now associate director; Dr. John Backus, physicist; Winfield W. Salisbury, electronics engineer. Top left is Dr. Luis W. Alvarez, noted physicist and group leader in the Laboratory, and Dr. Edwin M. McMillan, Nobel Laureate and present Director of the Laboratory. Dr. Alvarez leans against part of the magnet and half-sits on the housing for the coils; Dr. McMillan sits on one of the tanks holding the 'Dees' inside the accelerating chamber. The copper cylinders slanting down from right carry the power for the accelerating system."
