Timothy Dean

Timothy Dean was a student at Hulton College in 1914. He was often picked on by other students due to his smaller frame. He accidentally found the pod where the Seventh Doctor had stored his biodata while living as the human John Smith.

Leakage from the pod began to give Dean Time Lord abilities. When one of his classmates hung him, the respiratory bypass system he had developed saved his life.

When the Aubertides came looking for the pod, Dean was able to convince John Smith to become the Doctor again. Afterward, he lived a long life. Though fully human, Dean retained the best parts of the Doctor. (PROSE: Human Nature)

Behind the scenes
Timothy Dean was the basis, in part, for the character Tim Latimer in Human Nature / The Family of Blood. Both the novel and the TV story were written by Paul Cornell.
