He is best known for confirming the discovery of chromium by Vauquelin, and for independently discovering iridium in 1803.[1]

In 1806, Collet-Descotils misidentified erythronium, a new element discovered in Mexico by Andrés Manuel del Río, thinking that it was chromium. This resulted in Alexander von Humboldt rejecting Del Río's discovery.[2] The same element was rediscovered thirty years later in Sweden and renamed as vanadium.

In 1815, a few months before his death, he got the position of director of École des Mines de Paris, in charge of transferring the school to a new building. He is buried in the 10th Division of the Père Lachaise Cemetery of Paris.[3]
