1501 Baade (1938 UJ) is a main-belt asteroid discovered on October 20, 1938 by Wachmann, A. at Bergedorf.

Wilhelm Heinrich Walter Baade (March 24, 1893 – June 25, 1960) was a German astronomer who worked in the United States from 1931 to 1959.

Hermann Carl Vogel (1841-1907) was a German astronomer and spectroscopist. He invented an early scheme to classify stellar spectra and confirmed the sun's rotation. He directed the Potsdam Astrophysical Observatory from 1882 to 1907.

Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.

Edward Charles Pickering (July 19, 1846–February 3, 1919) was an American astronomer and physicist, brother of William Henry Pickering. Along with Carl Vogel, Pickering discovered the first spectroscopic binary stars.

Discovered by the Indiana Asteroid Program, Goethe Link Observatory, University of Indiana. This program was conceived and directed by F. K. Edmondson; the plates were blinked and measured astrometrically by B. Potter and, following her retirement, by D. Owings; and the photometry was performed under the direction of T. Gehrels. During the years 1947-1967, in which the plates were exposed, a large number of people participated in various aspects of the program.

George Ellery Hale (June 29, 1868 – February 21, 1938) was an American solar astronomer.

Edward Emerson Barnard (December 16, 1857 – February 6, 1923) was an American astronomer. He is best known for his discovery of Barnard's Star in 1916, which is named in his honor.

Nicolas Camille Flammarion (26 February 1842—3 June 1925) was a French astronomer and author. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and several works about Spiritism and related topics. At the age of nineteen, he published his first work, La Pluralité des Mondes Habités, which caught the public taste and was at once translated into several languages. From 1862 to 1866 he was attached to the Bureau des Longitudes.

Named in memory of John A. Brashear (1840-1920), maker of astronomical telescopes and scientific instruments, popularizer of astronomy and university administrator. Brashear contributed much to the siting, design and fundraising for the Allegheny Observatory, and his firm constructed its 0.76-m refractor and 0.79-m Keeler reflector. He figured the 0.4-m photographic doublet with which Max Wolf discovered many minor planets.

Samuel Pierpont Langley (1834-1906), third secretary of the Smithsonian Institution, was founder of its Astrophysical Observatory. While Allegheny Observatory director he invented a bolometer. He developed a working wing and in 1896 conducted the first successful flight of an unmanned, heavier-than-air flying machine.

Samuel P. Langley was named an Honorary Member of the Astronomical and Physical Society of Toronto on 1894-01-09.
