Jules Carpentier was born in Paris, France back in 1851. While I don’t have a lot of information on his schooling apparently, he was a very smart man. He was one of the first manufactures of the galvanometer which was an electromechanical instrument for detecting an electrical current. That instrument was in use for over 50 years.
He was also instrumental in helping the French with their telegraph system. Working with Charles Cros he helped produce one of the first color photography. He died in a car accident in Joigny, France in 1921. What you may not know about Jules is that in 1900 he developed the first periscope for use in submarines. By 1906, he had made over 80 of them. He was also given credit for the development of periscopes used in the trenches of WWI. Until tomorrow keep a smile on your face and a penny in your pocket
