Theophilus Tolliver

Theophilus Tolliver (who preferred to be called Theo) was a British inventor in the 19th century who invented a time machine. During his second trip through time, he was captured by Andron, taken to 3550 New Britain and imprisoned. After the Doctor was imprisoned with him, they worked together to escape execution and overthrow Mar-Kom. Afterwards, Theo returned to his own time, where he told his friend H.G. Wells about his adventures. (TVC: The Eternal Present)


 * The implication is that Theo is the protaganist of The Time Machine. Although he says he invented his time machine in 1897, Wells actually wrote the novel in 1895, so an invention date of 1887 would be more likely.
