Nicholas E. Wagman
Beginning in 1930, Wagman was associated with Pittsburgh's Allegheny Observatory. He was director of the Observatory and also chairman of the University of Pittsburgh's Astronomy Department from 1941 until 1970. Under his direction, the 0.76-m Thaw refractor was renovated and used to set the standard for parallax determinations, of which over 1200 were made. Many binary stars were also discovered and characterized.
