The Time Machine was a book by H.G. Wells from the late 19th century about time travel aboard a time machine.
When Kathryn Janeway tried to explain his true nature to the holographic Michael Sullivan in 2376, she inquired if he had read The Time Machine. (VOY: "Spirit Folk")
Daniels's claim in ENT: "Shockwave, Part II" that Jonathan Archer is "thinking of time travel like we're in some H.G. Wells novel" is apparently a reference to this book.
Trek alumnus Whit Bissell played Walter Kemp in the 1960 adaptation and Ralph Branly in the 1978 adaptation. Wah Chang designed the iconic titular object and the Morlocks for the former.
