H.G. Wells, Playboy of the Literary World
In 1914, during WWI, H.G. Wells coined the term "The War That Will End War." By 1923, for a New York Times Magazine profile article, he accurately predicted that the next world war would occur between 1940 and 1960.
Ernest Brennecke, Jr. interviewed Wells in London:
"The world is at the present time drifting into an era of Humor, an Era of Fun," he deliberated, falling into a prophetic mood. "We've had our fill of tragedy, high seriousness, and storm and strife for the present, and we're about to enter into a lighter period of existence. The world is now sick of wars and tumults and is looking for lighter entertainment, in order to forget the Inferno it has just passed through. Immediate dangers are not so terribly pressing: we are all simply anxious for diversion. Between now and 1940 or 1960, when the nations will be tested by their next bloody tragedy, they will look chiefly for fun.
"And so I am now at work on the kind of writing that I used to do, the sort of thing which provides me with the most fun."
Now in the public domain, Wells' 1914 The War that Will End War is available to read for free on Google Books:
