Named in memory of Frank Schlesinger (1871–1943), Director of the Allegheny Observatory from 1905 to 1920 and then Director of the Yale University Observatory until his retirement in 1941. His pioneering work in photographic astrometry revolutionized the determination of stellar parallaxes and the preparation of zone catalogues. His invention of the method of dependences for parallax reductions has also found extensive application in obtaining minor planet positions. He was prominent in the establishment of the IAU and served as its president from 1932 to 1935. (M 3934)
Schlesinger is also honored by a lunar crater.
