Born a French Huguenot, I became a private math tutor who befriended Newton and Halley.

Though recognized as a member of the Royal Society and the Academies in Berlin and Paris, I was never able to be hired as a University professor.

In between my long tutoring sessions, I wrote papers and published the book Doctrine of Chances (1718).

In contrast to today's approach, I derived the theory of permutations and combinations from the tenets of probability.

My eponyms include the idea that the probability of a compound event is the product of the probabilities of its components, and the connection of trigonometry to finding imaginary roots.

I was a member of the committee charged with the task of determining who should be credited with the invention of calculus -- Newton or Leibniz.

Answer: Abraham De Moivre, 1667-1754
