Fletcher Pratt, or more precisely, Murray Fletcher Pratt, lived an intriguing life. Seriously, look him up. The man moved in the right circles. Over there, Isaac Asimov, over here, Rex Stout. A true man of letters, making his living as much with non-fiction as with fiction. History, reviews, short stories, novels. Pratt was a man of accomplishment. And I’m sure Gary Gygax was familiar with Pratt’s development of rules for wargaming naval combat, using the tiles of his kitchen floor for grid squares.
