I didn’t know Ted very well. I met him last year, when I spoke at the Middle School Math Fest he organized in Madison. I expected to lecture to a dozen or so overachieving and dutiful students — instead, I found the CUNA cafeteria packed with close to a hundred pre-teens, still fizzy and enthusiastic after a full morning of math activities led by an equally energetic cadre of teachers and high school students from Madison East. And Ted, fizzier if possible than the pre-teens themselves, at the center of it all. Very few people have the drive and know-how even to put together an event like this, let alone to make it such a success. Madison was lucky to have somebody like Ted helping young students find joy in math; from the Cap Times article linked above, it sounds like the students who learned from Ted in the classroom were pretty lucky too.
