Thomas Ollive Mabbott (July 6, 1898 – May 15, 1968) was an American professor and scholar of literature, perhaps best known for his research on writer Edgar Allan Poe.
He has also done studies on John Milton, Walt Whitman, Thomas Chatterton, and Edward Coote Pinkney.
After graduating from Columbia, Mabbott taught English literature and composition at Northwestern University.
[3] He may be best remembered as an expert on Edgar Allan Poe, whose works he was in the process of compiling when he died on May 15, 1968, at the age of 69.
In 1967, during research for The Complete Works of Poe, Mabbott discovered a lost Walt Whitman poem titled "No Turning Back", one of only four he is known to have written in 1842.
