Mark Twain
From Tardis Wiki, the free Doctor Who reference
Mark Twain was an author. At some point, the Doctor had edited Twain's first draft of Huckleberry Finn. Twain was apparently horrible at spelling, and the Doctor's editing was what made him able to submit the manuscript. As a reward, he gave the Doctor an original Paul E. Wirt pen.
