Sir Mortimer Barnett Davis (February 6, 1866 – March 22, 1928) was a Jewish Canadian businessman and philanthropist. The mansion that he built in Montreal's Golden Square Mile has been renamed Purvis Hall and is today owned by McGill University. Business career Born in Montreal, Quebec, to Samuel Davis and Minnie Falk Davis, he graduated from the High School of Montreal and then joined his elder brothers Eugene Harmon and Maurice Edward in the family's cigar business, S. Davis and Sons. In 1888, S. Davis and Sons purchased another Montreal firm, D. Ritchie and Company. In 1895, the American Tobacco Company purchased D. Ritchie and Company, as well as the American Cigarette Company, another Montreal cigarette manufacturer. Samuel Davis retired from S. Davis and Sons, and Mortimer Davis left the family firm, which remained in the hands of two of his brothers, to become president of the American Tobacco Company of Canada. In 1902, the British-American Tobacco Company Limited was formed by the merger of the American Tobacco Company and the Imperial Tobacco Company of England. It later purchased the American Tobacco Company of Canada, which became the Imperial Tobacco Company of Canada Ltd., and Mortimer Davis was its first president. The financial power of the empire over which he presided earned him the title of "Tobacco King," which he shares with his great rival, Sir William Christopher Macdonald. In 1917, he was knighted by King George V, becoming the first Canadian-born Jew to receive such an honour. Davis was a director of many companies, including the Union Bank, Royal Bank of Canada, Henry Corby distillery (he served as president from 1907 to 1922), Crown Trust Company, Empire Tobacco, and part of the senior management of the Nova Scotia Silver Cobalt Mining Company and the Consolidated Asbestos Mining Company. In addition, he was a member of the Montreal Board of Trade and the Montreal Stock Exchange. Personal life On June 12, 1898, in San Francisco, Davis married Henriette Marie Meyer, daughter of Charles Meyer, a banker and philanthropist. Their only son, Mortimer Davis, junior, died in 1940. Davis was a member of Temple Emanu-El (see Temple Emanu-El-Beth Sholom (Westmount, Quebec)), which his father had helped to establish. He underwrote the entire $420,000 of a new YMHA (see Federation CJA) building, which opened at Mount Royal, near Park Avenue, shortly after his death. He was a key force in building the
