Clarence Tillenius (1913–2012) was a renowned Canadian nature artist, celebrated for his wildlife paintings and commitment to conservation. Born in Manitoba, he developed a passion for drawing animals from an early age. Despite losing his right arm in a 1936 accident, he continued to paint with his left hand, honing his skills under artist Alexander J. Musgrove. Tillenius traveled extensively across North America, observing wildlife in their natural habitats, which inspired his work. His art was featured in publications, museum dioramas, and commissions, including the "Monarchs of the Canadian Wild" series. A Fellow of the Explorer’s Club and the Royal Geographical Society, he received numerous accolades, including the Order of Canada. Tillenius’s work is housed in private and public collections worldwide, with a permanent heritage collection at Winnipeg’s Pavilion Gallery.
