John Walter Christie (May 6, 1865 – January 11, 1944) was an American engineer and inventor. [1] He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 [3] tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
The Christie M1931, known as the Combat Car, T1 in US Cavalry use and Medium Tank, Convertible, T3 in Infantry branch, was a wheel-to-track tank designed by J. Walter Christie for the United States Army using Christie's ideas of an aero-engine and the novel Christie suspension to give high mobility.
The Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed.

The Christie Company was originally called Christie Iron Works, but the name was changed in 1906. Christie was America's first exponent of front-wheel drive. [2] In 1904, he took a four-cylinder, 30 hp racer to Daytona Beach with an early front-wheel drive system. In all, six racers were built, two with 60 hp engines. [2]
In the early 1930s, American engineer J. Walter Christie experimented with the concept of a self-powered flying tank. Christie's design had a detachable set of wings attached to the roof of a lightly armoured tank and a propeller driven by the tank's engine. A prototype without wings was constructed, but the concept was never developed further ...
The following team was chosen to represent America: Joseph Tracy (90-hp. Locomobile), Hubert LeBlon (115-hp. Thomas), H.N. Harding (50-hp. Haynes), Frank Lawell (110-hp. Frayer-Miller), and J.
