H. G. Wells 
The Time Machine 

The Time Machine is a science fiction novella by H. G. Wells, published in 1895 and written as a frame narrative. 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.
The Time Machine has been adapted into three feature films of the same name, as well as two television versions and many comic book adaptations. It has also indirectly inspired many more works of fiction in many media productions.
