Watchmaker mechanic and swiss inventor.

Georges-Auguste Leschot is taken on as production engineer in 1839 and proceeds to revolutionize watch-making techniques by adapting the pantograph to the requirements of his industry. He also produced complicated musical clocks, as well as making artificial limbs (prosthesis of artificial limbs). He also invented a wheel-cutting machine for watch movements and built a device to demonstrate the theory of watch movement gearing. His invention of draw in lever escape wheel contributed to the universal adoption in the watch industry worldwide. He also invented a 'diamond drill' for rock piercing and deep well drilling. This invention was patented in 1862 and facilitated the piercing of a majority of tunnels in the world, such as the 'GOTHARD' in the Swiss Alps, as well as oil deep well drilling. This method is still used today worldwide.
