Caption: Portrait of Cecil Powell (1903-1969), English physicist and Nobel Laureate. Powell was the son of a gunsmith. He studied at Cambridge, gaining his PhD for his work with CTR Wilson on cloud chambers. After this, he went to Bristol. In the 1930's he started to use photographic plates to record the passage of charged particles. The tracks may be studied under a microscope, and Powell used them to estimate the mass, charge and energy of the particles concerned. This work led to his discovery of the pi-meson (pion) in 1947, predicted by Yukawa in 1935. This represented the start of modern high-energy particle physics, and led to Powell's 1950 Nobel Prize.
