Bramah Joseph Diplock

Bramah Joseph Diplock was an English inventor who invented the pedrail wheel in 1903 and the pedrail chaintrack, a type of caterpillar track, in 1910.

Diplock founded the Pedrail Transport Company of Fulham which was, before World War I, the only British company to manufacture "caterpillar" continuous tracks. A demonstration of the system's ability to support a large load for trench warfare was made on 16 February 1915 to Winston Churchill, and may have been influential in the development of the tank.
