Professor Anthony Hewish (b.1924), British radio astronomer and Nobel Laureate. Hewish studied physics at Cambridge, and became involved in the design of radio telescopes. In 1967 he and Martin Ryle completed a radio telescope with which he studied the scintillation of quasars - very distant but very bright galaxies. In the course of this work, Hewish and his assistant Jocelyn Bell discovered a regularly-pulsing radio source within our galaxy. This was the first pulsar to be found, a rotating collapsed star which sends out a lighthouse-like beam of radio waves. Hewish and Ryle won the 1974 Nobel Prize for Physics for this work. Photographed in 1993.
