Laboratory of Molecular Biology after their formal retirement including: Max Perutz, following an undergraduate training in organic chemistry, left Austria in 1936 and came to the University of Cambridge to study for a PhD, joining the X-ray crystallographic group led by J.D. Bernal. Here, in the Cavendish laboratory, he started his lifelong work on hemoglobin. The death of Lord Rutherford led to his successor, Lawrence Bragg, a pioneer in X-ray crystallography, becoming the new Cavendish professor of physics in 1938. Bragg became a major supporter of Perutz and his group in those early days. After World War II, many scientists from the physical side
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
