Theodore Bruce was born in
Leeds, Yorkshire, a son of William Bruce, a large woollens manufacturer. A grandfather,
Edward Baines, was the proprietor of the
Leeds Mercury and member of the House of Commons for Leeds. He came to Australia with his parents in 1852, and shortly after his arrival commenced his elementary education at J. L. Young's
Adelaide Educational Institution, followed by
St Peter's College. His first employment was at a station in the far north of the South Australia, then in 1862 he joined
Randolph Isham Stow in the law firm of Stow & Bruce, followed around 1872 by the National Bank of Adelaide, which required him to travel around the north of the State, during which time he became an expert horseman. His father, son of a Congregationalist minister in
Wakefield, Yorkshire set up as a merchant in Adelaide in 1852 and retired in 1863, returned to England in 1876, and died at
Ilkley in 1893, aged 96. His mother died in 1890. In 1878 or 1880 he started an auctioneering business with old school-friend
George S. Aldridge, later chairman of the
Stock Exchange. They founded a brewery in Broken Hill, which Bruce managed, then in 1888 sold to the
South Australian Brewing and Wine and Spirit Company. The partnership was dissolved in 1889, and Bruce continued as auctioneer on his own, with offices in the Old Exchange, Pirie street. He became a member of the Adelaide Stock Exchange. The business continues under his name to this day. ==Politics==
