I've always wanted to write. But not until I discovered the old science-fantasy magazines, at the age of sixteen, did this general desire become a specific urge to write science-fantasy adventures.  
I took a lot of on the way. I discovered s-f in its golden age: the age of Kuttner, C. L. Moore, Leigh Brackett, Ed Hamilton and Vance. But while I was still collecting slips for my early efforts, the fashion changed. Adventures on faraway worlds and strange dimensions went out of fashion, and the new look in science-fiction—emphasis on the science—came in.
 
So my first stories were straight science-fiction, and I'm not trying to put down that kind of story. It has its place. By and large, the kind of science-fiction which makes tomorrow's headlines as near as this morning's coffee, has enlarged popular of the modern, world of science we live in. It has helped generations of young people feel at ease with a rapidly changing world.
 
But fashions change, old loves return, and now that Sputniks up the sky with new and moons, the readers of science-fiction are willing to wait for tomorrow to read tomorrow's headlines. Once again, I think, there is a place, a wish, a need and hunger for the wonder and color of the world way out. The world beyond the stars. The world we won't live to see. That is why I wrote THE DOOR THROUGH SPACE.
