L. Sprague de Camp (1907 - 2000)
Lyon Sprague de Camp was born in 1907 and died in 2000. During a writing career that spanned seven decades, he wrote over a hundred books in the areas of science fiction, fantasy, historical fiction, non-fiction and biography. Although arguably best known for his continuation of Robert E. Howard's Conan stories, de Camp was an important figure in the formative period of modern SF, alongside the likes of Isaac Asimov and Robert A. Heinlein, and was a winner of the Hugo, World Fantasy Life Achievement and SFWA Grand Master awards.

P. Schulyer Miller (1912-1974)
Peter Schuyler Miller was an American science fiction writer and critic. Miller was raised in New York's Mohawk Valley, which led to a life-long interest in the Iroquois Indians. He pursued this as an amateur archaeologist and a member of the New York State Archaeological Association.
He received his M.S. in chemistry from Union College in Schenectady. He subsequently worked as a technical writer for General Electric in the 1940s, and for the Fisher Scientific Company in Pittsburgh from 1952 until his death.
Miller died October 13, 1974 in Blennerhassett Island, West Virginia. He was on an archaeological tour to the 'Fort Ancient Civilization' site west of Parkersburg at the time.
