““Recently there came a period when I had little to do. This was novel in a life so crammed with busy years, and I decided to amuse myself by writing a novel that was pure science fiction. In the hard-driven times between 1930 and 1950, I was a professional writer not simply because it was my job, but because I wanted to finance more serious researches. In those days there were few agencies pouring out large grants to independent workers. Despite what you might hear about Roosevelt “relief,” those were depression years. One succeeded or one starved.””
