The Time Machine is an 1895 dystopian, post-apocalyptic, science fiction novella by H. G. Wells about a Victorian scientist known as the Time Traveller who travels to the year 802,701. 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.
