The Dominion Astrophysical Observatory, Victoria, B.C.

About the author
Born near Woodstock, Ontario, in 1865, John Stanley Plaskett did not begin as a professional astronomer. He studied at the University of Toronto, worked as a mechanic and instrument maker, and brought that practical skill into scientific work when he joined the Dominion Observatory in Ottawa in 1903.
Plaskett became a leading force in Canadian astrophysics through his work in stellar spectroscopy, using and improving instruments to measure the motions and properties of stars. He strongly advocated for the creation of the Dominion Astrophysical Observatory in Victoria, helped design its principal instruments, and served as its first director beginning in 1917.
Remembered as both a careful observer and a gifted builder, he played a major role in establishing astrophysical research in Canada. He died in Victoria, British Columbia, in 1941.
