Mathematician
American amateur mathematician who discovered the $10$th and $11$th Mersenne primes $2^{89} - 1$ (in $1911$) and $2^{107} - 1$ (in $1914$.)
In $1916$, he determined that $2^{241} - 1$ is composite.
Very little is known about R.E. Powers. He lived in Denver, Colorado from at least 1911 to 1916.
