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 Professor of Physics something of a contradiction, dressing as a Victorian gentleman but working on the cutting edge of physics. Rutherford died suddenly in 1937, marking the end of an era for the Cavendish. Sir Lawrence Bragg became Cavendish Professor just before the outbreak of the Second World War, which resulted in many staff joining various defence research establishments, notably to develop radar. Work on neutron physics performed at this time was translated into the Manhattan Project to build an atom bomb. In 1971 it was renamed from the "Cavendish Professorship of Experimental Physics" to the "Cavendish Professorship of Physics". Until Brian Pippard
