Christopher Marlowe

Christopher "Kit" Marlowe was the greatest Elizabethan tragedian writer besides William Shakespeare.

Biography
The Ninth Doctor made passing reference to Rose Tyler that Marlowe was gay or bisexual, and that the Doctor would be willing to make a pass at him if the situation called for it. (COMIC: A Groatsworth of Wit) Marlowe, in fact, flirted extensively with the First Doctor's companion Steven Taylor. (PROSE: The Empire of Glass)

Marlowe, Edward Kelly, and William Shakespeare were supposedly involved in some trouble with Psionovores invading through a scrying stone. (PROSE: Apocrypha Bipedium)

Though history recorded that Marlowe died in 1593, this was wrong. In fact, Marlowe had travelled to the colony of Roanoke in the future United States to spy on Sir Walter Raleigh. While there, he and the rest of the colony were abducted by the Greld, who would use them in their plan to sabotage the Armageddon Convention. He actually died in 1609 as a result of a duel. (PROSE: The Empire of Glass)

A different account stated that Marlowe had "died" on 13 May 1593, but that in reality the Fourth Doctor was posing as Marlowe and pretended to die, to allow history to take its course. Marlowe then assumed his alternate identity, William Shakespeare. (PROSE: All Done with Mirrors)

Behind the scenes
Christopher Marlowe is yet another perfect example of how the Doctor Who universe differs from the real world. Marlowe actually died on thirty May, not thirteen as in the DWU.
