12 de ene. de 2021 · "Walter Baade was one of the key players in mid-20th Century astrophysics and this biography by Donald Osterbrock is welcome and timely. . . . His story is a fascinating one, well told and nicely illustrated with contemporary photographs."—David Strickland, The Observatory
Walter Baade was born one hundred and one years ago; he died in 1960, a third of a century ago. In my opinion he was the second most important observational astronomer of this century, after Edwin Hubble, who changed our place in the universe and our perception of it. I will give some of the evidence in this paper.

WALTER BAADE 23 met in Germany in 1922, and with whom he had been corresponding on globular-cluster research. Shapley, director of Harvard College Observatory, helped Baade obtain a Rockefeller Fellowship to spend a year in the United States, 1926-27, during which he worked at Harvard, Yerkes, Lick, DAO, and (most of the time) Mount Wilson.
Wilhelm Heinrich Walter Baade fue un astrónomo alemán que emigró a los Estados Unidos en 1931. Entre otros aportes, definió el concepto de población estelar, descubrió diez asteroides y la existencia de dos tipos de Cefeidas, lo que llevó a una importante corrección en la escala de distancias extragalácticas.

German-born US astronomer, who made valuable contributions to knowledge of stellar and galactic evolution. The son of a schoolteacher, Baade was educated at the universities of Munster and Göttingen, where he obtained his PhD in 1919.
