Who is Mr. Briggs from Hidden Talents and what is their importance?

Mr. Briggs teaches science at Edgeview. He initially wanted to work for a chemical company or to teach at a more prestigious school, but his teaching methods and the way he dresses have caused him trouble in these areas. Mr. Briggs, however, cares deeply about his students, and he is the only teacher who can see past Martin's hurtful words and see the goodness inside. Mr. Briggs becomes Martin's without ever becoming aware of the special talents Martin and his friends share.
