Thaddeus Maine was a professor from Halifax. He invented a time machine for historical research and used to travel to the "dawn of Time" and the "end of days." In September 1894, he intended to perform a demonstration of it at the Academy of Science, but after various attempts to steal the machine and kill Thaddeus, Madame Vastra insisted the time machine be deactivated because no nation could handle its power. Thaddeus sadly agreed, but instead of deactivating the time machine, he got inside and travelled away. (PROSE: The Singular Case of the Time Machine)
