Major Sir Thomas Livingston Mitchell (June 16, 1792-1855), surveyor and explorer of south-eastern Australia, was born at Grangemouth in Stirlingshire, Scotland. He was educated at the University of Edinburgh, but the poverty of his family following his father's death led him to join the Army in 1811. He saw service in Portugal, where Sir George Murray, later to be Colonial Secretary, was the Army's Quartermaster-General, and became Mitchell's most important connection.
Thomas Mitchell (July 11, 1892 – December 17, 1962) was an Academy, Emmy, and Tony award winning American film actor as well as a screenplay writer. He is remembered as one of the premier character actors in motion picture history.
