He is similar to my ancestor who was a professional baseball player who was inducted into the baseball Hall-of-Fame. The top level category is sports. Baseball is one of the sub-categories under sports. Then, within baseball, you have a wide range of sub-categories that are specific to baseball (specific teams, the Hall-of-Fame, etc.). In our current form, my ancestor appears in two sub-categories under baseball (St. Louis Browns and Baseball Hall of Fame).
For Ralph Waldo Rose, the top level catgeory would be sports. Track and Field should be one of the sub-categories under sports. Then, within track-and-field, you would have a range of subcategories that would be relevant to track and field, such as specific events, Olympics, world record holder, etc. - as there are numerous people out there who could be classified under these categories. Ralph Waldo Rose should be in sub-categories under track and field (Shot Put, World Record Holders, Olympians, Olympic Gold Medalists).
