## 1908-2001

Wilfrid Mann received his B.Sc. in math and physics from Imperial College London in 1930 and his Ph.D. in physics from the University of London in 1934. His thesis was on the exchange of energy between a platinum surface and gas molecules. He received a D.Sc. from the University of London in 1951. He did graduate research on cyclotron and artificial radioactivity at the University of California, Berkeley, from 1936-38. During his time at Berkeley, Mann discovered the radioisotope gallium-67, which is much used today in nuclear medicine. He did graduate research on electrostatic generators at Imperial College London from 1938-46. Mann was hired by L.S. Taylor to head the Radioactivity Section at the National Bureau of Standards (NBS, now the National Institute of Standards and Technology, NIST) in 1951.
