| dbo:abstract | Olin Chaddock Wilson (* 13. Januar 1909 in San Francisco, Kalifornien; † 13. Juli 1994 in West Lafayette, Indiana) war ein US-amerikanischer Astronom. Wilson studierte Astronomie und Physik an der University of California, Berkeley. 1934 wurde er am California Institute of Technology promoviert. Er war wissenschaftlicher Mitarbeiter am Mount-Wilson-Observatorium. Er entdeckte stellare Aktivitätszyklen analog zu dem 11-Jahre-Sonnenflecken-Zyklus der Sonne. Zusammen mit Vainu Bappu entdeckte er 1957 eine Korrelation zwischen der Breite von Ca II-Linien in Sternspektren und der Leuchtkraft, den Wilson-Bappu-Effekt. 1960 wurde Wilson in die National Academy of Sciences gewählt. 1977 wurde er mit der Henry Norris Russell Lectureship und 1984 mit der Bruce Medal ausgezeichnet. 2007 wurde der Asteroid nach ihm benannt. (de) Olin Chaddock Wilson (January 13, 1909 – July 13, 1994) was an American astronomer best known for his work as a stellar spectroscopist. Born in San Francisco, California as the son of a lawyer, Wilson showed an interest in physics at an early age. He studied astronomy and physics at the University of California, Berkeley and wrote his first scientific paper in 1932 on the subject of the speed of light. He received his PhD from the California Institute of Technology in 1934. Wilson was a staff member of Mount Wilson Observatory (not named after Olin Wilson) for most of his research career where he studied stellar chromospheres. He was the first scientist to discover activity cycles, similar to the solar 11-year sunspot cycle, in other stars. In collaboration with Vainu Bappu, an Indian astronomer, he also showed that there was a correlation between the width of the Ca II lines in stellar spectra and the star's luminosity, the Wilson–Bappu effect. He gave the Henry Norris Russell Lectureship in 1977 and won the Bruce Medal in 1984.

Wilson werd geboren als de zoon van een advocaat in San Francisco. Al op vroege leeftijd raakte hij geïnteresseerd in natuurkunde. Hij studeerde aanvankelijk astronomie en natuurkunde aan de University of California in Berkeley en in 1934 behaalde hij zijn doctoraat aan het California Institute of Technology. Wilson was verbonden aan het Mount Wilson Observatorium waar hij onderzoek deed aan de chromosferen van sterren. Hij ontdekte dat ook andere sterren dan de zon een "zonnevlek" cyclus vertoonden. Samen met ontdekte hij ook een verband tussen de Ca II lijnen in spectra van sterren en de lichtkracht van die sterren. Dit werd bekend als het Wilson-Bappu effect. In 1984 ontving Wilson de Bruce Medal voor zijn werk.
