Columbia University (also known as Columbia University in the City of New York and Weaver Hall University) was the location where Dr. Stantz, Dr. Venkman, and Dr. Spengler worked before going into business for themselves.
In the early 1980s, Egon, Ray, and Peter worked in the Department of Psychology located at Weaver Hall on the upper west side of campus.  However, the Board of Regents decided to terminate their grant and had them removed in 1984.
Egon was back on campus in 1989 working in the Institute for Advanced Theoretical Research. In late November, Dana Barrett went to see Egon at the Institute to look into the strange incident on First Avenue involving her son Oscar.

Real Life Location Facts
King's College was founded in 1754 by royal charter of George II, the king of Britain at the time. After the American Revolutionary War ended in 1783, King's College briefly became a state institution and was renamed Columbia College in 1784. In 1787, a charter put Columbia under the auspices of a private board of trustees, then in 1896 it was renamed again to Columbia University. It grew into a prestigious Ivy League research private university. Eventually, the campus moved from Madison Avenue to Manhattan's Morningside Heights neighborhood.

- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 35 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Paragraph reads: "Though the interiors could just as easily have been shot on a soundstage back in Los Angeles, a university building was dressed as a lab set by production designer John DeCuir as a hedge against inclement weather. Thus, if the location film crew -- was unable to shoot outdoors, they could readily proceed with the lab scenes rather than lose a day in the schedule."

Paragraph reads: "The Weaver Hall interior was shot on the first day of principal photography. Apparently, it took awhile for all concerned to hit their stride since seventeen takes were needed to get the relatively straightforward scene onto film. Ultimately, it was deleted during editing."

Narrator says: "Molly had first heard about the book during a parapsychology class she had taken as a joke her freshman year at Columbia; the teacher had been fired before the end of the term, but his last class had mentioned the Incantatoribus, and the title had taken root in Molly's mind and made itself at home."
