Not a historical figure, but interesting anyway. Perhaps you know that Dan Harris, TV reporter, also belongs to the club. He wrote a book you can get from the library. "10% Happier, how I tamed the voice in my head, reduced stress without losing my edge, and found self-help that actually works--a true story." It is a charming book, easy to read, makes us smile, helps us realize we are not alone. He is a fellow meditator.
As to Lincoln, I've read he also suffered bouts of depression. We are in good company.
