John Stanley Plaskett (November 17, 1865 – October 17, 1941) was a Canadian astronomer.

Contents

He worked as a machinist, and was offered a job as a mechanician at the Department of Physics at the University of Toronto, constructing apparatus and assisting with demonstrations during lectures. He found this so interesting that at the age of 30 he enrolled as an undergraduate in mathematics and physics. He stayed at the university until 1903, doing research on color photography.

His formal astronomical career did not start until 1903, when he was appointed to the staff at Dominion Observatory in Ottawa. He measured radial velocities and studied spectroscopic binaries, and performed the first detailed analysis of galactic structure. His mechanical background was very useful for constructing various instruments. He became first director of the Dominion Astrophysical Observatory in Victoria, British Columbia in 1917 (not to be confused with the old Dominion Observatory in Ottawa).

His son, Harry Hemley Plaskett, also pursued a very successful career in astronomy, winning the Gold Medal of the Royal Astronomical Society in 1963, thereby making the Plasketts one of the very few families to boast more than one Medal winner.
