Eratosthenes of Cyrene (276 BCE - 194
BCE) was BCE), a Greek mathematician
(among other things),
and was chief librarian of the Great Library of
Alexandria. He also devised a system of latitude and longitude, and
was the first known person to have calculated the circumference of the Earth.
He also invented a method of finding Prime
Numbers Numbers, called the Sieve Of Eratosthenes, that doesn't require
division (although most people implement this incorrectly and do use division.)
