Albert Bushnell Hart

Albert Bushnell Hart (July 1, 1854 – July 16, 1943) was an American historian, writer, and editor based at Harvard University. One of the first generation of professionally trained historians in the United States, a prolific author and editor of historical works, Albert Bushnell Hart became, as Samuel Eliot Morison described him, "The Grand Old Man" of American history, looking the part with his "patriarchal full beard and flowing moustaches."
