Biography

Early life

Pierre André Latreille was born on November 29, 1762 in the town of Brive

When the prison's doctor inspected the prisoners, he was surprised to find Latreille scrutinising a beetle on the dungeon floor. When Latreille explained that it was a rare insect, the physician was impressed, and sent the insect to a 15-year old local naturalist, Jean Baptiste Bory de Saint-Vincent

In the following few years, Latreille was especially productive, producing important papers for the , all of the volume on arthropods for George Cuvier's ("The animal kingdom"), and hundreds of entries in the on entomological subjects. As Lamarck became blind, Latreille took on an increasing proportion of his teaching and research work. In 1821, Latreille was made a knight of the .
