Who is Timmy Heidi from Do Black Patent-leather Shoes Really Reflect Up?: A Fictionalized Memoir and what is their importance?

Timmy attends St. Bastion's grammar school with Eddie and is also attending Bremmer High School. Since he has the "nerve" to question the nuns throughout grammar school, they declare him stupid, punishing him with low grades. When he takes the special scholarship exam for high school, however, he achieves the highest score of the two hundred participants, and receives a full scholarship. The nuns at St. Bastion, of course, are in shock. Timmy is one of eleven children, his parents taking very seriously the notion of procreation. As well, Timmy's house has no radio or television, a condition brought about by his father, who feels they are signs of lack of intelligence. Unlike the other "nerds" in the Honors Program at Bremmer, Timmy is much more well-rounded, loving baseball and his small group of close friends, none of whom are in the honors program with him.
