Frank W. Dyson, the son of a minister, won scholarships to secondary school and Cambridge University, where he studied mathematics and astronomy. Dyson spent his entire career, except for five years in Edinburgh, at the Royal Greenwich Observatory, where he was Director and Astronomer Royal from 1910 to 1933. At Greenwich he directed measurements of terrestrial magnetism, latitude, and time, and he initiated the radio broadcast of time. He determined proper motions of northern stars and completed his portion of the international Carte du Ciel project of photographing the entire sky. Dyson is best known for directing (with Arthur Stanley Eddington) the 1919 eclipse expedition which confirmed the bending of starlight by the sun's gravity, as predicted by Einstein's general theory of relativity.
