Otto Struve

Born 12 Aug 1897; died 6 Apr 1963 at age 65. Russian-American astronomer who was a fourth generation astronomer, the great-grandson of Friedrich Struve. He made detailed spectroscopic investigations of stars, especially close binaries and peculiar stars, the interstellar medium (where he discovered H II regions), and gaseous nebulae. He contributed to the understanding of the broadening of spectral lines due to stellar rotation, electric fields, and turbulence and worked to separate these effects from each other and from chemical abundances. He was a pioneer in the study of mass transfer in closely interacting binary stars. Struve emigrated to the USA (1921) and joined the Yerkes Observatory, Wisconsin, becoming its director in 1932.«
