Founder and director of Steward Observatory's mirror lab at the University of Arizona, Tucson, Roger Angel (b. 1941) has spearheaded the development of telescope mirrors as large as eight meters in diameter by a process called spin-casting. His work and ideas have resulted in an enormous increase in telescope light-gathering power.
