Harold Frank Milton Arthur (12 December 1908 in Lismore, New South Wales – 11 September 1972 in Sydney)[1] was a former international motorcycle speedway rider who won the first Star Riders' Championship, the forerunner of the Speedway World Championship, in 1929.

[4] Arthur born in Lismore, New South Wales started work as a farm hand before taking up speedway.

He brought Max Grosskreutz over from Australia in 1929 and supplied Dicky Case and Ray Tauser with machines and support for fifty percent of their earnings.

[7] He promoted speedway in the United States, and he was also involved in the business side of the sport in Australia, where he helped Max Grosskreutz to start his career.

He solved this problem by building the speedway track at the Sydney Sports Ground next door.
