Florence Berger, a Cornell University professor who found a second calling as a pro bono matchmaker, leading her to successfully arrange some two dozen marriages, died on July 13 at her home in Charlottesville, VA. She was 83.

          Ms. Berger was a popular presence on the Cornell campus, where she became an expert in the hospitality industry, teaching courses in organizational behavior, human relations and creativity, writing three academic books, and gaining distinction as the first woman to be elevated to full professor at the hotel administration school. But she was perhaps best known for matchmaking. She arranged marriages over more than four decades, almost all of which endured, according to her son, Larry. The only couple that divorced was the one that didn’t invite her to the wedding, he said.
