André Citroën's Double Helical Gear

Origin
Inspired by the steampunk works of Jules Verne and industrial exhibition of the Eiffel Tower, André Citroën pushed to become an engineer. After graduating from university, he bought a pair of unique fish-bone structure gears that produced less noise and performed better than existing styles. He scooped them up and developed them as his own double helical gear, working flawlessly in heavy machinery. Citroën applied this innovation first to arms production during World War I and later to manufacturing the revolutionary car brand named after him.
