George A. Van Biesbroeck, Astronomer
George A. Van Biesbroeck (1880-1974) at Yerkes Observatory, watching (through a 40-inch refracting telescope) Mars when it approached close to the earth in 1926. Van Biesbroeck was a Belgian-American astronomer. He discovered the periodic comet 53P/Van Biesbroeck, as well as two non-periodic comets: C/1925 W1 (Van Biesbroeck 1) and C/1935 Q1 (Van Biesbroeck 2). He also discovered sixteen asteroids. In 1961 he published the Van Biesbroeck's star catalog. In this he cataloged a number of very faint stars, known by the VB numbers he assigned to them upon discovery. One notable star he discovered was the very small red dwarf secondary star, VB 10, also known as Gliese (GJ) 752B, of the primary star, Wolf 1055 (Gliese (GJ) 752A).
