Early Life and Education
Pierre François Marie Auguste Dejean was born in Amiens, France on August 10, 1780. He initially pursued a career in medicine but soon transitioned to military service.
Military Career
Dejean played an active role in various military campaigns and battles. During the Battle of Waterloo in 1815, he served as an adjutant to Napoleon Bonaparte. After the war, he faced exile briefly before returning to France and taking a seat in the Chamber of Peers.
Entomology
Despite his military career, Dejean's true passion lay in entomology, particularly the study of beetles. He began collecting beetles as a hobby during his youth and continued to do so even during military campaigns. He traveled extensively to acquire new specimens, purchasing and exchanging collections.
Achievements in Entomology
Dejean's systematic catalog of beetles, published in two volumes, remains a significant contribution to entomology. He described numerous new species and revised the classification of beetles, significantly advancing the field.
Legacy
Dejean's vast collection of beetles, comprising over 170,000 specimens, is considered one of the most comprehensive in Europe. His work has had a lasting impact on the field of entomology, and he is widely recognized as one of the most influential beetle specialists of his time.
