Irving Stern, high school Computer science- influenced my college choice, and eventual career choice. Irreverant and eccentric. I spent most lunchtimes and free periods in his room. I continued to visit his classroom and attend his annual end-of-year picnics years after graduation.
John Glaze, high school Calculus- an amazing teacher. Pulled students out of homeroom and held class during various other downtimes, to get an amazing passing rate on the AP exam. Expert and professional, he often seemed aloof, but always knew exactly what everyone iin the room was doing, and how well they were doing.
