The Dictionary of Australasian Biography/Bull, John Wrattall
Bull, John Wrattall, son of the late Rev. John Bull, M.A., incumbent of St. John's, Walthamstow, England, was born at St. Paul's Cray, Kent, on June 23rd, 1804. He emigrated to South Australia in 1838, and engaged successfully in pastoral pursuits, but was ruined in the crisis caused by the dishonour of Governor Gawler's drafts. He went to the Victorian gold diggings in 1852, but returned to Adelaide the next year, when he became manager of Mr. Osmond Gilles' Glen Osmond property, where he established a vineyard, one of the first in the colony. In 1842 he invented a locomotive steam-threshing machine, and in 1882 was voted £250 by the South Australian Parliament for his improvements in agricultural machinery. He was the author of "Bull's Experiences of Colonial Life." He died on Sept. 21st, 1885.
