Cavendish Laboratory worked with Crick at Cambridge in the Cavendish Laboratory and the new Laboratory of Molecular Biology. According to the late Dr. Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA. Orgel also later worked with Crick at the Salk Institute for Biological Studies. The Cavendish Professors were the heads of the department until the tenure of Sir Brian Pippard, during which period the roles separated. † "Jacksonian Professors of Natural Philosophy" Areas in which the Laboratory has
Cavendish Laboratory new chemistry building with the Department of Chemistry (led by Lord Todd) in Lensfield Road: both chemistry departments merged in the 1980s. In World War II the laboratory carried out research for the MAUD Committee, part of the British Tube Alloys project of research into the atomic bomb. Researchers included Nicholas Kemmer, Alan Nunn May, Anthony French, Samuel Curran and the French scientists including Lew Kowarski and Hans von Halban. Several transferred to Canada in 1943; the Montreal Laboratory and some later to the Chalk River Laboratories. The production of plutonium and neptunium by bombarding uranium-238 with neutrons was predicted
