Midge’s father Abe used to teach mathematics at Columbia University, with students who would follow him at the drop of a hat. After quitting last season, he returns to his old classroom where the students are clearly still petrified of him. The exterior shots of Columbia University are not filmed there, but the classroom we saw in previous seasons. It’s located in 309 Havemeyer Hall at Columbia University.
This is considered one of the most filmed classrooms because it has appeared in numerous television shows and movies, including the Spiderman films and Kinsey. It fits 330 students and has the cool moveable chalkboards.
