RALPH KOPPERMAN: I received my Ph.D. from M.I.T. in 1965, and came to The City College in 1967. SEEK is a special program for students from poor areas of the city, and I have coordinated its mathematics efforts since 1969. My research interest has always been in limits, which I first tried to study through infinitary languages (logic). I was able to publish in the field, but was not happy with the results of that research, and went into point-set topology in 1980. I was a founding member of the CCNY Seminar on General Topology and Topological Algebra in 1981, and have been involved with it ever since.
