By the book trivia

[Rob Wick]

There have been a slew of biographies written about Abraham Lincoln. I am in the process of working on a book about one of the four that I call "The Four Horsemen," i.e., Ida Tarbell, Albert J. Beveridge, William E. Barton and, of course, Carl Sandburg.

However, this question is not about any of them. The question here is, who was the first academician to write a biography of Lincoln. It was not James G. Randall, by the way.
