P Schuyler Miller

Finally, I've tracked down (or at least had time to track down) a bio of Mr. Miller.

Some highlights are that he died in 1974, and besides the few links I've previously listed, it seems he was a chemist and worked for the famous Preiser Scientific. Man, I've purchased a lot of stuff from them over the years.

If you cross paths with a copy of Analog, Feb 1975 there's an article by Sam Moskowitz that details Miller's SF career.
