@Googler Thanks for the clarification. I’d appreciate any additional details you could offer. I was basing my statements on the following bits of information:

1) “By 1915, the Columbia University Club had outgrown its quarters on Gramercy Park and was looking for a larger clubhouse in Midtown, where many other clubs were settling. The Club purchased the old Renaissance Hotel at 4 West 43rd Street and made extensive renovations to transform it into a fine clubhouse. The Club’s new quarters included an impressive dining room, a bar and grill, lounges, a library, a billiards room, a gym, squash courts and almost seventy-five bedrooms.”

2)”The Columbia University Club began to struggle in the 1960s, an era of diminished alumni involvement, student unrest and deep problems for New York City. By 1973, the Club was no longer considered a viable institution and the clubhouse at 4 West 43rd Street was sold to the World Unification Church.”

3) “However, interest in a Columbia alumni club in New York City did not altogether disappear and began to increase in the 1980s. During this time, the Club was reconstituted and found shelter at the National Women’s Republican Club, the Williams Club and then, beginning in 1998, at the Princeton Club, just across the street from its old home.”

4) “Not long after the Columbia Club extended its hospitality during the construction of our current Clubhouse, the Princeton Club was able to return the favor. In 1973 the officers of the Columbia University Club found it necessary to dissolve their club completely. The Princeton Club invited many of the Columbia Club members to apply for Associate Membership in The Princeton Club and several hundred accepted the invitation. Now, in a similar fashion to our Brown and Dartmouth colleagues of the 1930’s and 40’s, the Columbia Club is in full residence at the Princeton Club of New York, sharing its facilities and adding vibrancy to our membership.”
