High Quality Content by WIKIPEDIA articles! Otto Struve (August 12, 1897, Kharkiv, Ukraine April 6, 1963, Berkeley, USA) was a Ukrainian - Russian-American astronomer. In Russian, his name is sometimes given as Otto Lyudvigovich Struve ( ); however, he spent most of his life and his entire scientific career in the United States. Otto Struve 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. He was a member of the Struve family, the son of Gustav Wilhelm Ludwig Struve, grandson of Otto Wilhelm von Struve and great-grandson of Friedrich Georg Wilhelm von Struve, who were Russian astronomers of ethnic German origin. He was also the nephew of Karl Hermann Struve.
