I was home-schooled by my father, an ex-private in the French army...who also encouraged me to become a physician.
When 18, I entered the Ecole Polytechnique and studied under both Laplace and Lagrange...with both becoming my good friend for the rest of my life.
According to historians, I am known for my comment that "Life is only good for two things: to do mathematics and to teach it."
My primary contributions to mathematics are in probability, with my eponym being an important probability distribution.
My most remembered publication was Researches on the Probability of Criminal and Civil Verdicts.
Simeon Denis Poisson (1781-1840)
