Joseph Lakanal

Born 14 Jul 1762; died 14 Feb 1845 at age 82.French educator who reformed the French educational system during the French Revolution. He was a respected scientist of the time, and observed the development of the telegraph by Ignace Chappe. On 2 Jul 1793, Joseph Lakanal filed a report to the legislature on Chappe's behalf, requesting officially that the mayors of the three communities where the first telegraphs were being erected would be ordered to take measures for the protection of the telegraphs. On 25 Feb 1795, Joseph Lakanal defined on behalf of the French Revolution an “educational utopia”which would “put an end to inequalities of development that affected a citizen's capacities for judgment.”
