Mathematician:Frank Nelson Cole

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 in which he performed the necessary arithmetic on a blackboard without saying a single word.

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