Mr. Dimming

Also known as Mr. D, he teachers history and is the coach for the Whiz Kids team. He is an enthusiastic teacher and loves his job, but he doesn’t initially believe that Melody can participate in class, much less score highly on his tests. He allows Melody onto the Whiz Kids team and makes accommodations for her, but in the end he allows the Whiz Kids team to leave for DC without her, demonstrating that he never truly accepted her as an important member of his team.
