Early life

Lenormand was born in Montpellier in 1757 as the son of a watchmaker. From 1775-1780 he studied physics and chemistry under Lavoisier and Berthollet in Paris, where he was also involved with the administration of saltpeter. In this position he learned from the use of scientific and mathematical knowledge in the production of gunpowder. After returning to Montpellier he worked in his father's store while immersing himself in the intellectual community of the city and began his experiments with skydiving, acrobatic performance inspired by Thailand that uses an umbrella for balance. Before you make the leap from the observation of public, Lenormand parachute tested using animals.

Career as "professor of technology"

After this public demonstration Lenormand devoted himself to building a science of "pure technology". For this purpose, he first became a Carthusian monk, the monastery in the near Castres Saix allow him to continue the "profane" his study. If during the French Revolution he had left the priesthood and married, he moved to Albi to teach technology at a new college founded by his father-in-law.
