Ulysses

Daniel Joyce was the name used by a Time Lord who became a professor on Earth.

Biography
On Earth, he adopted the name Daniel Joyce and lived in Berkeley near San Francisco, where he married his wife, Anne. He became a professor and taught at Berkeley University. Sometime in the 1980s, Joyce assisted the Doctor with a danger related to the Advanced Research Project that Joyce was working for. Joyce later hired Larna as his assistant on the Project.

After the millennium he gave Professor Wagg a new beryllium chip to make up for the one that was stolen from him. In 2002, Joyce assisted the Eighth Doctor (whom he called "son") in defeating Griffin and in closing a dimensional scar. Joyce told the Doctor that he had begun experimenting with his biodata at this time, but refused to tell him why. He called the Doctor "son". (PROSE: Unnatural History)

Appearance
On Earth, Joyce had a tattoo indicating that he had once been imprisoned on Shada. He also had a short white beard and a Scottish accent. (PROSE: Unnatural History)

Behind the scenes

 * In The Gallifrey Chronicles, the character Ulysses, who originated as the Doctor's father in Philip Segal's proposed late 1990s revival of Doctor Who, last appears in the company of Larna, Daniel Joyce's assistant. In real life, author James Joyce wrote a novel called Ulysses.
 * It was commonly speculated by fans that Joyce was a later incarnation of Professor Chronotis from Shada, the existence of which almost certainly inspired the character. However, this was later denied by writer Jonathan Blum.
 * Joyce was to feature in a Doctor Who novel by Kate Orman, but the novel was never published.
