Clyde Lorrain Cowan (1919-1974), US physicist. Cowan received his doctorate in 1949 from Washington University in St Louis, Missouri, USA. He then joined the Los Alamos Scientific Laboratory, Mexico, USA. He worked with Frederick Reines, carrying out what is now called the Cowan-Reines neutrino experiment. By 1956 enough data had been gathered to confirm the existence of the neutrino (the particle detected was the electron antineutrino). Cowan died before he could be honoured for this work. Reines was awarded the 1995 Nobel Prize in Physics, acknowledging Cowan in his recipient's speech. Photographed on 5 May 1958.
