Caption: Georges-Louis Le Sage (1724-1803). 1868 illustration of the Swiss physicist Georges-Louis Le Sage. Le Sage is best known for his theory of gravitation, his invention of an electric telegraph and his anticipation of the kinetic theory of gases. He attempted to use static electricity in 1774 for signalling, part of early experiments on wire telegraphy, where he used an electrostatic generator to generate the charge. Electric pulses were sent down wires and measured with an electroscope. Le Sage used 24 wires, each representing a letter of the alphabet. Le Sage's system worked, but was impractical and not adopted. Practical electric telegraphy was invented in 1837.
