It was who demonstrated in $1876$ that $2^{127} - 1$ is prime.

He was able to do this by using a new technique he designed, which was a precursor to the Lucas-Lehmer Test.

He himself expressed some doubt over the fact of this result, but it was confirmed in $1914$ by.

This number held the record for the highest known prime number for longer than any other: $1876$ to $1952$, when discovered the prime nature of $2^{521} - 1$.

It also remains the largest prime number to be discovered without the help of modern electronic calculation machines.

To put the question into perspective, the author of this page used an online integer factorization calculator to find out the prime numbers immediately before and after $2^{127} - 1$ in a matter of seconds.
