Who is George M. Heinholz from Welcome to the Monkey House and what is their importance?

George is the band director at Lincoln High School. A nice, fat man about 40 and married. He loves music. He loves it absolutely and more than anything. He is sure that his band is the best band in the world. He is so sure of this that he has convinced the school board and everyone else to buy them the best uniforms and instruments they can. Heinholz gives every ounce of himself to his band, and he is unshakable in his belief in the healing power of music. This all unravels, though, when Heinholz meets Jim. Jim is a brand of teenager Heinholz has not encountered. Jim's supreme apathy unsettles Heinholz. When he catches Jim defacing the school at night, Heinholz is downright sickened. He is at a loss about how to help Jim. All he can do is offer up his most prized possession—the John Phillip Sousa trumpet. When Jim begins to crack a little, Heinholz is there to catch him. He holds Jim close and he takes Jim's boots. He will not give them back because "they are bad for him."
