In 1802, Jean Alexandre, a reputed natural son of Jean Jacques Rousseau,
brought out a TELEGRAPHE INTIME, or secret telegraph, which appears to
have been a step-by-step apparatus. The inventor concealed its mode of
working, but it was believed to be electrical, and there was a needle
which stopped at various points on a dial. Alexandre stated that he had
found out a strange matter or power which was, perhaps generally
diffused, and formed in some sort the soul of the universe. He
endeavoured to bring his invention under the eye of the First Consul,
but Napoleon referred the matter to Delambre, and would not see it.
Alexandre was born at Paris, and served as a carver and gilder at
Poictiers; then sang in the churches till the Revolution suppressed this
means of livelihood. He rose to influence as a Commissary-general, then
retired from the army and became an inventor. His name is associated
with a method of steering balloons, and a filter for supplying Bordeaux
with water from the Garonne. But neither of these plans appear to have
been put in practice, and he died at Angouleme, leaving his widow in
extreme poverty.
Sommering, a distinguished Prussian anatomist, in 1809 brought out a
telegraph worked by a voltaic battery, and making signals by decomposing
water.
