Clyde Tombaugh

born 1906 - died 1997

Discoverer of dwarf planet Pluto
He used this telescope to make fine sketches of Mars and Jupiter, and sent the drawings to the Lowell Observatory, for comment (they are still there today), he was offered a job as an assistant. Tombaugh continued searching the skies at Lowell Observatory over the next 13 years, with time out for a college education. No more planets showed up, but he discovered six star clusters, two comets, hundreds of asteroids, several dozen clusters of galaxies and the super-cluster of galaxies stretching from Andromeda to Perseus. In 1932 he discovered a nova in Corvus that had exploded a year earlier.
