david westin. >> thank you. what i have here is not an official memorial. i wanted to share a few thoughts from some teachers and students of mr. david westin's. he went into teaching later in life and that is an interesting perspective when someone starts teaching after 35. they have done a lot of living and decided they want to teach now and that is david westin's road and he spent 12 years as a teacher at their good marshall perfecting -- thurgood marshall in mathematics and science. in my time in 2000 through 2004, he rode his bike through the city before was fashionable. this is an example that grownups can ride their bike to school and not guzzle gas as adults and i get a lot of disinformation also in here from a former thurgood marshall teacher. he lost his quiet battle to leukemia. he was meeting with alumni students about the reunion and even the students about -- could not believe it. they had met with him weeks before. he was adamant about remaining in the classroom. one student says, i had mr. weston for geometry and he was the first teacher to show me the importance of perfection in mathematics. and what it meant.
