Charles CrosDied 9 Aug 1888 at age 45 (born 1 Oct 1842).(Émile-Hortensius-) Charles Cros was a French inventor and poet whose work in several fields foreshadowed or paralleled important developments. He was interested in mechanical and physical sciences. He designed an automatic telegraph and showed it at the World Fair of 1867. He sent to the Société française de photographie, in 1869, a system for reproduction of color images. Also, he delivered viable plans on 18 April 1877 to the Académie des Sciences, for an apparatus called a paléophone, which was the principle of the gramophone. Thus, he had the idea before Edison. Nevertheless, he died in poverty and was never recognized for his discoveries in his lifetime, due to more influential and better funded competitors. |
