Cecil Frank Powell, FRS (5 December 1903 – 9 August 1969) was a British physicist, and Nobel Prize in Physics laureate for his development of the photographic method of studying nuclear processes and for the resulting discovery of the pion (pi-meson), a subatomic particle.Powell was born in Tonbridge, Kent, England, the son of a local gunsmith, and educated at a local primary school before gaining a scholarship to the Judd School, Tonbridge, which now has one of its four houses named after Powell (the house colour is green), and awards the Powell Physics and Mathematics Prize to an upper sixth form student every year in his honour.
