Why Is Wallace L. W. Sargent Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Wallace Leslie William Sargent was a British-born American astronomer and the Ira S. Bowen Professor of Astronomy at California Institute of Technology. Education Sargent was born in Elsham, North Lincolnshire, the son of a gardener and a housecleaner, and grew up in Winterton, Lincolnshire. Sargent was the first person in his family to attend high school, and the first student from his high school to ever attend college. He received his bachelor's degree from the University of Manchester in 1956, and his Ph.D. in 1959 from the same institution.
