Sir George William Ross 1841-1914
Born in Middlesex County, Ross was a teacher and school inspector before entering law and politics. Having represented West Middlesex as a Liberal member of the House of Commons (1872-83), he entered provincial politics, was Minister of Education (1883-99), and became premier in 1899. Precariously surviving the election of 1902, his defeat in 1905 marked the end of 34 years of Liberal rule in Ontario. Called to the Senate in 1907 he was Liberal leader there from 1911 until his death. An outstanding public speaker, he was also the author of several works on politics and education. He died at Toronto.
