Named in memory of Nicholas E. Wagman (1905-1980), American astronomer and leading astrometrist. Associated with the Allegheny Observatory beginning in 1930, he was its director and the 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; and a number of astrometric binaries were discovered and characterized. In his honor the Amateur Astronomers Association of Pittsburgh named its Nicholas E. Wagman Observatory in 1976. Name proposed and citation prepared by T. P. Kohman on behalf of the association.
