The Eloi are one of the two fictional post-human races, along with the Morlocks, in H. G. Wells' 1895 novel The Time Machine.

The Time Machine is a post-apocalyptic science fiction novella by H. G. Wells, published in 1895. The work is generally credited with the popularization of the concept of time travel by using a vehicle or device to travel purposely and selectively forward or backward through time. The term "time machine", coined by Wells, is now almost universally used to refer to such a vehicle or device.
