According to Wikipedia, Champ Summers is a nickname for Major league Baseball play John Junior Summers. There's an article on his death at OCALA if you want more information.
The 1947 National League batting champion was Harry William "the Hat" Walker, who played for both the St. Louis Cardinals and Philadelphia Phillies during the season and posted a remarkable .363 batting average, .436 on base percentage, and 16 triples, all league leads. Ironically he had only 1 homer and 41 RBI's, all of which came in Philadelphia, yet this was not enough to deter him from the honor as home runs and RBI's were much less common back then.
