Haro, Guillermo (1913–1988)
Guillermo Haro was a Mexican astronomer best known as the co-discoverer of Herbig-Haro objects and for important work on flare stars, blue galaxies with line emission (see Haro galaxy), and stellar evolution and formation, and, most importantly, for putting Mexico on the astronomical map. Haro grew up amid the turbulence of the Mexican Revolution and began his early studies in law. After discovering astronomy through the motivation of L. E. Erro, Haro left law and became his assistant. From 1943 and 1947 he carried out research in the United States at Harvard College Observatory, Case Observatory of the University of Chicago, and McDonald Observatory. Subsequently he served as director of the Observatory Astronómico de Tacubaya, the Instituto de Astoronomia, and the Observatory Astronómico Nacional. He also started the project to establish the Observatory of San Pedro Mártir, Baja California, in 1968, which now bears his name.
