When your youngster scribbles down a list of things he wants Santa Claus to bring its a pretty safe guess that high on the list is a sleek slim device of steel and wood, a sled. This is the story Samuel L. Allan, who in 1885 invented the modern sled, added the word belly-whopper to the dictionary and turned out to be Kris Kringle's little helper.
