Sir George Alfred Julius (29 April 1873 – 28 June 1946) was an English-born New Zealand inventor and entrepreneur.

George Alfred Julius was born in a small house in Bethel Street, Norwich, England, (demolished in the 1930s to make way for the new City Hall).

Later, Churchill Julius became vicar of Holy Trinity, Islington, London; he subsequently accepted the appointment as Archdeacon of Ballarat, Australia, and it was here that the family travelled on the sailing ship South Australian in 1884.

While working for the Government Railways, George Julius conducted a series of tests on timber and wrote two learned papers on Western Australian hardwoods.

This research led to a job offer from Allen Taylor & Co Ltd, a timber company in Sydney, as part-time engineer.

The first installation of the totalisator was at Ellerslie Racecourse, Auckland, New Zealand in 1913, which was entirely manual in operation, and the second at Gloucester Park Racetrack in Western Australia, electrically driven.

One of the great contributions made by George Julius to the advancement of Australian technology resulted from his appointment, in 1926, as chairman to the Council for Scientific and Industrial Research (CSIR).
