Who is this person?

Who is this?
   

[J. Beckert]

Dennis Hanks?

[Eva Elisabeth]

Good guess, Joe, but it's not him.

[Eva Elisabeth]

Hint #1: Try to imagine him without the beard. Whom does he resemble?

[RJNorton]

This is going to get to me, Eva. I definitely have seen that image in a book, but my mind has gone blank. Salmon P. Chase with a beard?

[Eva Elisabeth]

Another good guess, Roger, but it isn't Chase either.
Hint #2: He supposedly died in 1830.

[RJNorton]

Eva, your second clue helped. Mordecai Lincoln.

I was going to say John Hanks, but he died in 1889.

[L Verge]

Is Mordecai the one who was married to a Mudd?

[RJNorton]

Yes, good memory, Laurie. He married Mary Mudd. Wikipedia says Mary Mudd was a first cousin twice removed of Dr. Samuel Mudd.

[Eva Elisabeth]

You've got it, Roger, very good! He does resemble Thomas, doesn't he?

[Rob Wick]

Inquiring minds want to know...who is this gentleman?

[L Verge]

With that stern a face, it sure isn't Santa Claus!

[RJNorton]

James Harlan as an older man?

[Rob Wick]

Good guess Roger, but it isn't Harlan. And Laurie is correct that it isn't Santa Claus.

First clue: He corresponded with several Lincoln biographers.

Rob

[RJNorton]

Worthington C. Ford?
