Jean-Henri Casimir Fabre was a French entomologist and author. He was born in St. Léons in Aveyron, France. Fabre was largely an autodidact, owing to the poverty of his family. Nevertheless, he acquired a primary teaching certificate at the young age of 19 and began teaching at the college of Ajaccio, Corsica, called Carpentras. In 1852, he taught at the lycée in Avignon.
