Curtis Niles Cooper is an American mathematician. He currently is a professor at the University of Central Missouri, in the Department of Mathematics and Computer Science.
Using software from the GIMPS project, Cooper and Steven Boone found the 43rd known Mersenne prime on their 700 PC cluster on December 15, 2005. The prime, 2 − 1, is 9,152,052 digits long and is the ninth Mersenne prime for GIMPS.
Cooper and Boone became the first GIMPS contributors to find two primes when they also found the 44th known Mersenne prime, 2 − 1, which has 9,808,358 digits (or M32582657 for short). This prime was discovered on September 4, 2006 using a PC cluster of over 850 machines. This is the tenth Mersenne prime for GIMPS.
