Person-of-Mystery

Welcome to Cipher Saturday!  You've found the home of everyone's favorite weekend pastime, where a stylized photo of a somewhat famous person from history is provided here for you to identify.

Additional clues may be found in the cipher below:

ABBBBBAAABABBBAAAAABABABBAABAAABBAAABAAA ABBBBAABAABAAAB ABAAAABABB AAABBBABAAAAABAAABAA

So, who could I be?  That's the mystery!  Go ahead and take a guess and then go enjoy your day.  Check back tomorrow and I'll reveal the answer.  The first correct post will be declared the winner.

If you'd like to make sure that your guess is correct, enter his name into Google Images and this photo will be found on the first pages of the image results.

Today, I'm again out of reach, backpacking with the Boy Scouts, so I cannot comment on your guesses, but I hope to be back tomorrow sometime.
