Otto Struve

Otto Struve, 1959

Otto Struve, (1897 - 1963) was one of the few eminent astronomers in the pre-Space Age era to publicly express a belief that extraterrestrial intelligence was abundant, and so was an early advocate of the search for extraterrestrial life. Otto Struve completed his Ph.D. dissertation in 1923 and became director of Yerkes Observatory at the University of Chicago. He subsequently directed four different observatories in all, in addition to serving as editor of the Astrophysical Journal and authoring numerous books. Struve was also president of the International Astronomical Union.
