J Walter Christie was born in 1865 and began work at the age of 16 in an Iron works. His varied career included consultant engineer for steamship lines, a design for a front wheel drive car and even later manufacturing fire engine tractors.
Of course he is most renowned for his design of the “helicoil” suspension system, where each wheel had its own spring loaded assembly; this allowed tanks much longer movement than conventional “leaf spring” design. The result was to improve cross country speeds and achieve a lower profile.
Most notably utilized on the Soviet BT Series and its direct successor the T34.
Ironically none of Christie’s designs ever saw mass production in the USA. He passed away a poor man in 1944 at the time when his designs were shaping world history.
