## Mathematician

American mathematician famous for finding the factors of the Mersenne number $M_{67}$. (It had already been demonstrated by Édouard Lucas in $1876$ that it is not prime, but till this time the factors had not been found.) Cole's demonstration of this in $1903$ took the form of a now famous lecture On The Factorization of Large Numbers in which he performed the necessary arithmetic on a blackboard, delivering the only totally wordless lecture in recorded history.

The American Mathematical Society's Cole Prize was named in his honor.
