Book Description
John Stanley Plaskett was Canada’s pre-eminent astronomer in the first half of the twentieth century. His legacy lives on in the observatory he founded in Victoria, British Columbia, and the reputation he built for Canada as a nation making vital contributions to basic science. Plaskett’s pioneering work with the most massive stars and his definitive determination of the rotation of the Milky Way Galaxy earned him international recognition of the highest order. Northern Star explores Plaskett’s unorthodox and fascinating life from his rural roots near Woodstock, Ontario through his days as a technician at the University of Toronto to his initiation in astronomy at the Dominion Observatory in Ottawa. His greatest achievements followed after he persuaded the government of Canada, in spite of the strictures of the First World War, to finance what was then the world’s largest operational telescope. Peter Broughton’s accessible and engaging prose illuminates Plaskett’s numerous achievements and the social, political, economic, and religious milieu surrounding them. This richly illustrated volume invites readers to understand the pull that Plaskett’s passions, personality, and motivations exerted on him during his lifetime.

Book Description
Excerpt from The Dominion Astrophysical Observatory, Victoria, B. C: A Sketch of the Development of Astronomy in Canada and of the Founding of This Observatory; A Description of the Building and of the Mechanical and Optical Details of the Telescope; An Account of the Principal Work of the Institution The order for the large disc for the 72-inch mirror and for an auxiliary flat of 55 inches diameter for testing the 72-inch was given to the St. Cobain Glass Works of Paris by the Jno. A. Brashear Co. As soon as the contract was awarded. The 72-inch disc was cast and annealed by June 1914 and was fortunately shipped at once without waiting for the 55-inch disc. It left Antwerp only about a week before war was declared and it was only by this small margin that Canada now has a 72-inch telescope. Grinding and polishing were at once begun but the lack of the large flat and other difficulties delayed the completion and it was not until April 1918, about a year and a half after the completion of the mounting, that the figuring was finally completed and the telescope ready for work. Nevertheless, for an undertaking of such magnitude the work was completed in record time, four and a half years after the awarding of the contracts.
