Who is this person?

I am taking a wild stab at this based on my perception that the gentleman is African American. Many years ago, a Canadian member of the Surratt Society supplied us with a very interesting biography of a black surgeon by the name of Anderson Abbott, who was born in Canada after his free black parents fled Alabama. Abbott went on to become the first Canadian-born black surgeon.

When our CW began, he signed on as a civilian contract doctor with the Union forces and served for several years at the Freedman's Hospital in D.C. and also one in nearby Virginia. He also became friends with President Lincoln and is said to have been one of the first African Americans to attend one of the White House parties. There is also a story that he accompanied Elizabeth Keckly to the Petersen House on the night of the assassination, however, it appears that Mrs. Keckly did not reach that home until the next morning. Later, it is said that Mrs. Lincoln gave Dr. Abbott the plaid shawl that President Lincoln had worn at his first inaugural.

So, my guess is that this is Dr. Anderson Abbott. And, if I'm wrong, you have had my history lesson for the day anyhow.
