- William Lewis Elkin
William Louis Elkin (April 29, 1855–May 30, 1933) was an American
astronomer .He was born in
New Orleans to Jane and Lewis Elkin, one of five children but the only one to survive to adulthood. Following the death of her husband in 1867, Jane travelled abroad for the following seventeen years, taking along William. As a result of a broad education, he learned to speak fluently in German and French, and acquired a basic understanding of Italian and Spanish. He also received a broad knowledge of music from many nations,and would retain a deep love of music for the remainder of his life.He became seriously ill in 1870, possibly from
dysentery , and thereafter he would suffer health problems for the remainder of his life. In 1872 he joined the Royal Polytechnic School inStuttgart , Germany, where he studiedcivil engineering , graduating in 1876. While at school, however, he gained an interest in astronomy and decided to make that his life's work. After graduation, he spent four years working at theStrassburg Observatory . In 1880 he was awarded a Ph.D. from theUniversity of Strasbourg , with a dissertation on the parallax ofAlpha Centauri .A year before Elkin left Strassburg, he had a meeting with the directory of the Cape Observatory, David Gill. The two men became fast friends and Gill extended Elkin an invitation to Cape Town. Dr. Elkin sailed for South Africa in December, 1880, arriving in 1881. While at the observatory, Gill and Elkin collaborated to measure
stellar parallax es. Theirefforts were noted for their particular accuracy, at least for that time period, and elimination of systematic errors. After studying the parallax of several first magnitude stars, Elkin made measurements of thePleiades , followed by some northern stars. In subsequent years, Gill and Elkin also performed parallax measurements of selectedasteroid s.In 1896 he married Catharine Adams, although the couple would not have any children. The same year Dr. Elkin became the director of
Yale Observatory . After a lengthy record of observations lasting about fifteen years, he retired at age 55, suffering from ill health.Awards and honors
