1878–1937
Known for detailed studies of Canadian rock formations and mining regions, this early 20th-century geologist wrote practical survey reports that helped map and explain parts of Ontario and Quebec. His work sits at the crossroads of science, field exploration, and public service.

by W. H. (William Henry) Collins
William Henry Collins (October 26, 1878 – January 14, 1937) was a Canadian geologist whose publications are often cataloged under "Collins, W. H. (William Henry), 1878–1937." He studied at the University of Toronto and later at Heidelberg, the University of Chicago, and the University of Wisconsin–Madison before building a long career with the Geological Survey of Canada.
Collins wrote and contributed to a range of geological reports, including studies of the Timiskaming region, the Onaping map-area, and other Canadian mining and rock formations. These works were closely tied to field research and government survey work, making them useful not just to specialists but also to the broader effort of understanding Canada's natural resources.
He eventually served as Director of the Geological Survey of Canada and was recognized by major scientific societies in Canada and Britain. A suitable verified portrait could not be confirmed from the sources reviewed, so no profile image is included.
