:''Not to be confused with his grandfather Otto Wilhelm von Struve (1819–1905)'' Otto Struve (August 12, 1897 – April 6, 1963) was a Ukrainian– astronomer. In Russian, his name is sometimes given as Otto Lyudvigovich Struve (Отто Людвигович Струве); however, he spent most of his life and his entire scientific career in the United States. Otto was the descendant of famous astronomers of the Struve family; he was the son of Ludwig Struve, grandson of Otto Wilhelm von Struve and great-grandson of Friedrich Georg Wilhelm von Struve. He was also the nephew of Karl Hermann Struve.〔 With more than 900 journal articles and books, Struve was one of the most distinguished and prolific astronomers of the mid-20th century. He served as director of Yerkes, McDonald, Leuschner and National Radio Astronomy Observatories and is credited with raising world-wide prestige and building schools of talented scientists at Yerkes and McDonald observatories. In particular, he hired Subrahmanyan Chandrasekhar and Gerhard Herzberg who later became Nobel Prize winners. Struve's research was mostly focused on binary and variable stars, stellar rotation and interstellar matter. He 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. ==Early years in Russia== Struve was born in 1897 in Kharkiv, the largest city of Sloboda Ukraine, then Russian Empire (now Ukraine), as the first child of Ludwig Struve and Elizaveta Khrystoforovna Struve (1874–1964). His astronomy experience started early: from the age of eight, he was accompanying father in the telescope tower and from 10 carried out some minor observations, despite his fear of the dark spaces. After having received home education, at the age of 12, Struve started attending a school in Kharkiv and showed mathematical talents. Otto was the first child of the Struve family in Russia who attended a Russian-speaking rather than German-speaking school, and was bilingual in German and Russian. After graduating in 1914, he continued his astronomy work. In June 1914, Struve took part in preparations for observation of a total solar eclipse (August 8, 1914) and later used that experience and results for his master's degree work defended in 1919 at Kharkiv University.〔Memoirs, p.352〕〔Osterbrock, p.77〕〔Balyshev Marat. Otto Ludwigovich Struve (1897–1963).- Moscow: Nauka, 2008. – 526 p.〕 Struve entered the Kharkiv University in 1915, at the time of political unrest and wars in Russia. In the beginning of 1916, just having finished the first semester, he interrupted his studies and enlisted to a military artillery school in St. Petersburg. He passed an accelerated training program, and in February 1917, was sent to the Turkish front. After the Treaty of Brest-Litovsk was signed, Struve returned to Kharkiv for a year between spring 1918 and spring 1919 and completed a full university course. in June 1919, he received a certificate signed by the rector of Kharkiv University stating that Struve will stay with the University to prepare for professorship at the department of astronomy and geodesics. During that time, Struve also worked at the "workshop school of fine mechanics" and obtained a license of a workshop trainer. The workshop was organized by his father with the goal of creating traditions of astronomy engineers in Russia. Those were non-existent and foreign engineers were personally invited from abroad for high-quality mechanical work.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Otto Struve」の詳細全文を読む スポンサード リンク
