Robert Grant Aitken ( December 31 1864 – October 29 1951 ) was an American Astronomer . He worked at Lick Observatory . He systematically studied Double Stars , measuring their positions and calculating their orbits around one another. He methodically created a very large catalog of such stars, with the orbit information enabling astronomers to calculate stellar mass statistics for a large number of stars. Aitken also measured positions and computed orbits for Comet s and Natural Satellite s of Planets . Aitken was partly Deaf and used a Hearing Aid . He married Jessie Thomas around 1888 , and had three sons and one daughter. His grandson, Robert Baker Aitken , is a widely-known Zen Buddhist teacher and author. HONORS Awards
