Born and educated in France, I graduated from the École Polytechnique and became a meteorologist in the French army.
Captured by Prussia while part of Napoleon III's army, I eventually was freed from jail to turn to teaching and doing research in mathematics.
My fame is tied to eponymic points, circle, and triangle, all of which takes too long to explain here.
Mathematician Nathan Court suggested that I, along with Émile Lemoine and Joseph Neuberg, co-founded the rich area now known as triangle geometry.
Known as a solitary figure with no close family, I never married and seldom entertained friends...but I did actively interact with my scientific peers.
