Robert Tait McKenzie (sometimes written MacKenzie) (May 26, 1867 – April 28, 1938) was a Canadian physician, educator, sculptor, athlete, soldier and Scouter. Born in Ramsay Township, Lanark County, Ontario, Canada, he attended McGill University in Montreal as an undergraduate and medical student, and was an instructor in its medical school beginning in 1894. In 1904, he moved to the United States to teach at the University of Pennsylvania in Philadelphia, Pennsylvania. In the 1930s, he returned to the county of his birth, retiring to the Mill of Kintail in Almonte. He pioneered physical fitness programs in Canada. During World War I, his methods and inventions for restoring and rehabilitating wounded soldiers laid a foundation for modern physiotherapy practices. Source: Wikipedia (en)
