John Stanley Plaskett (inset), born on a farm in southwestern Ontario two years before Canada became a nation, was nearly 40 years old when he began work at the Dominion Observatory in Ottawa.
Using the 15-inch refractor telescope, Plaskett was responsible for the design and use of spectroscopes to measure the radial velocity of stars.
Plaskett’s reputation as an internationally respected astronomer received a big boost in 1922 with his discovery of a massive binary star (previously regarded as a single star), which was, for many years, the heaviest on record.

In the early years, more than one medal was often awarded in a year, but by 1833 only one medal was being awarded per year.
This caused a problem when Neptune was discovered in 1846, because many felt an award should jointly be made to John Couch Adams and Urbain Le Verrier.
A controversy arose and no award was made in 1847.

As a result there is a change in the wavelength of the light from a star when there is a satellite moving around it even when the satellite is too dim to be visible.
That is what Plaskett had observed in the spectrum of Rigel A. But, since he hadn’t detected any spectral characteristics of the satellite, he assumed that the satellite was too faint for the capabilities of his spectrograph.
Like Plaskett, the observers of the visual satellite of Rigel B are also mistaken.

 District of Saanich: Significant Heritage Structures
The Dominion Astrophysical Observatory telescope was designed by Dr. John Stanley Plaskett, astronomer with the Department of the Interior in Ottawa.
Various areas in Western Canada were considered as possible sites for the observatory, but Saanich was chosen because of the stability of atmospheric conditions and the equability of year-round temperatures, more than for the clarity of its air.
John Charles Malcolm Keith, the architect of Christ Church Cathedral, designed the hall, C.H. Merkly built it for $4364, and D.L. Hickey and Company did the wiring for $288.
