On August 11, 1941, therefore, I began the story of that interregnum and called it "Foundation." In it, I described how the psychohistorian, Hari Seldon, established a pair of Foundations at opposite ends of the Universe under such circumstances as to make sure that the forces of history would bring about the second Empire after one thousand years instead of the thirty thousand that would be required otherwise.

The story was submitted on September 8 and, to make sure that Campbell really meant what he said about a series, I ended "Foundation" on a cliff-hanger. Thus, it seemed to me, he would be forced to buy a second story.

However, when I started the second story (on October 24), I found that I had outsmarted myself. I quickly wrote myself into an impasse, and the Foundation series would have died an ignominious death had I not had a conversation with Fred Pohl on November 2 (on the Brooklyn Bridge, as it happened). I don't remember what Fred actually said, but, whatever it was, it pulled me out of the hole.

"Foundation" appeared in the May 1942 issue of Astounding and the succeeding story, "Bridle and Saddle," in the June 1942 issue.

After that there was only the routine trouble of writing the stories. Through the remainder of the decade, John Campbell kept my nose to the grindstone and made sure he got additional Foundation stories.

"The Big and the Little" was in the August 1944 Astounding, "The Wedge" in the October 1944 issue, and "Dead Hand" in the April 1945 issue. (These stories were written while I was working at the Navy Yard in Philadelphia.)
