Harry Hemley Plaskett (July 5, 1893 - January 26, 1980) was a Canadian astronomer who made significant contributions to the fields of solar physics, astronomical spectroscopy and spectrophotometry. From 1932 to 1960, he served as the Savilian Professor of Astronomy at the University of Oxford, and in 1963 was awarded the Gold Medal of the Royal Astronomical Society.cite journal | title = Obituary - Plaskett, Harry-Hemley | last = Adams | first = M.G. | year = 1980 | journal = QJRAS | volume = 21 | pages = 486 | url = http://adsabs.harvard.edu/abs/1980QJRAS..21..486A]

Life

Harry Hemley Plaskett was born in Toronto, Ontario on July 5, 1893. His parents were Rebecca Hemley and John Stanley Plaskett, who at the time was working as a machinist in the Department of Physics at the University of Toronto, but who would later go on to become the first director of the Dominion Astrophysical Observatory, and a Gold Medal winner in his own right.

After receiving his B.A. from Toronto in 1916, he joined the Canadian Corps, serving in the field artillery in France from 1917-1918. Following this, and a year spent working with Professor Alfred Fowler at Imperial College, he returned to Canada, and was appointed to the staff of the Dominion Astrophysical Observatory in Victoria, B.C. In 1921, he married Edith Alice Smith, with whom he had two children, Barbara and John Stanley. They were to remain married until his death in 1980.cite journal | author = Millman, P.M. | title = Obituary - Plaskett, Harry-Hemley 1893-1980 | journal = Journal of the Royal Astronomical Society of Canada | year = 1980 | volume = 74 | pages = 234] In 1928, he was appointed Professor of Astrophysics at Harvard University, and in 1932 succeeded H. H. Turner as Savilian Professor of Astronomy at the University of Oxford. His time there was interrupted by war service: from 1939 to 1940, he was an anti-aircraft officer, and from 1940 to 1944 he worked on experimental navigation for the
Ministry of Aircraft Production. He retired from Oxford in 1960, becoming a Professor Emeritus of the university, but remained active in astronomical research almost until the end of his life.
