The Dominion Astrophysical Observatory, Victoria, B.C. is a comprehensive historical and scientific account detailing the conception, construction, and early achievements of one of Canada's most significant astronomical institutions. Authored by John S. Plaskett, the book chronicles the vision and efforts that led to the establishment of the observatory atop Observatory Hill near Victoria, British Columbia, in the early 20th century. It explores the motivations behind the project, the selection of the site, and the technical challenges overcome in building what was, at the time, one of the world's largest and most advanced telescopes—a 72-inch reflecting telescope. The narrative delves into the architectural and engineering feats required to house and operate such a powerful instrument, describing the observatory's design, the construction process, and the installation of the telescope itself. Plaskett provides insight into the scientific goals of the observatory, emphasizing its role in advancing knowledge of the universe, particularly in the fields of stellar spectroscopy and the study of the Milky Way. The book highlights the early research conducted at the observatory, including pioneering work on the structure and dynamics of our galaxy, and the contributions of Canadian astronomers to international science. Richly illustrated with photographs and diagrams, the book offers readers a vivid sense of the observatory's setting, equipment, and daily operations. It also reflects on the broader significance of the observatory for Canadian science and its place within the global astronomical community. The Dominion Astrophysical Observatory, Victoria, B.C. stands as both a tribute to scientific ambition and a detailed record of a landmark achievement in Canadian astronomy, capturing the spirit of discovery that defined an era.
