Sir Frederick Oscar Warren Loomis (1870–1937) enlisted as a private in the Canadian Militia in 1886 and served there until retiring in 1919. During the First World War he was given command of the Royal Highlanders of Canada and later led the 3rd Canadian Division during the last two months of the First World War as a major-general. He is portrayed in a painting in the Canadian Senate Chamber leading the Royal Highlanders of Canada (Canadian Expeditionary Force) into Saint-Nazaire in 1915. Mount Loomis on the Alberta/BC border is named after him.
