In Response to: The Oznot Project

Few Princetonians are aware that Joseph Oznot ’68 (feature, March 21) stayed at Princeton long after the rest of his classmates graduated. When my freshman roommates and I heard of him in the fall of 1971, we invited him to room with us, reasoning that the null set is an element of all other sets. He was not the best roommate — kept mostly to himself, never paid for beer. I lost track of him not long after.
