"The Time Machine is a true classic. Originally published in 1895, H. G. Wells’ short novel of time travel is one of the most beloved works in all of science fiction. Back when I was a twelve-year-old, I vividly recall watching the 1960 film with Mom and Dad at the local movie house. Traveling through time with the turn of the century scientist as he encounters first the Eloi and then the Morlocks proved to be among my most powerful childhood experiences.
