My eccentric great uncle passed away, and included a provision in his will that I should receive his entire estate If I can prove myself by breaking his encryption. He claims to be the descendant of a famous person from history. This is some kind of test to prove that I'm worthy, I suppose.

who famously wrote

Needless to say, I'm quite nervous right about now. Can you help me solve this puzzle?
