With Anticipations of the Reaction of Mechanical and Scientific Progress upon Human Life and Thought, generally known as Anticipations, H.G.

His most recent biographer, however, calls the volume "both the starting point and the lowest point in Wells's career as a social thinker."

The novel's hero is Bert Smallways, a "forward-thinking young man" and a "kind of bicycle engineer of the let's-'ave-a-look-at-it and enamel-chipping variety."

The Time Machine is a science fiction novella by H. G. Wells, published in 1895.

The term "time machine", coined by Wells, is now almost universally used to refer to such a vehicle. The Time Machine has since been adapted into two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It has also indirectly inspired many more works of fiction in many media.

At the time of the novel's publication in 1896, there was growing discussion in Europe regarding degeneration and animal vivisection. Several interest groups were formed to oppose vivisection, the two largest being the National Anti-Vivisection Society in 1875 and the British Union for the Abolition of Vivisection in 1898.
