[3] On February 23 the Buffalo Enquirer reported: "Pratt's father came on from Springville yesterday and it was practically decided to send the youth to the State Hospital for the Insane at Willard, pending an investigation of his case by the grand jury.
[5] After a stint at the Buffalo Courier-Express he settled in New York City in 1920 and worked for a Staten Island newspaper before turning to freelance writing in 1923.
Starting in the summer of 1937 Pratt became a regular at the annual Bread Loaf Writers' Conference in Vermont for the next 18 years, eventually becoming their Dean of Nonfiction.
Frequent guests and residents at Ipsy-Wipsy included William Lindsay Gresham, John Ciardi, William Sloane, Basil Davenport, Lester del Rey, Ted Sturgeon, Esther Carlson, Fred Pohl, John D. Clark, Willy Ley, Judith Merrill, Eugenie Clark, L. Sprague de Camp, and many others.
This was known as the "Fletcher Pratt Naval War Game" and it involved dozens of tiny wooden ships, built on a scale of one inch to 50 feet.
Noted author and artist Jack Coggins was a frequent participant in Pratt's Navy Game, and de Camp met him through his wargaming group.
In 1956, after his death, the Round Table's board of directors established the Fletcher Pratt Award in his honor, which is presented every May to the author or editor of the best non-fiction book on the Civil War published during the preceding calendar year.
[10] Aside from his historical writings, Pratt is best known for his fantasy collaborations with de Camp, the most famous of which is the humorous Harold Shea series, eventually published in full as The Complete Compleat Enchanter (1989, ISBN 0-671-69809-5).
Pratt's story "Dr. Grimshaw's Sanitarium" was adapted for radio drama by George Lefferts, and broadcast twice: first on Dimension X (September 22, 1950) and then on X Minus One (July 14, 1955).
