Nov. 16, 1966: As the Viennese Opera Ball loomed, Liselotte Waldheim — daughter of the Austrian ambassador — and a dancing partner were on hand to demonstrate the Viennese waltz, lest the young couples invited to the annual event, which benefited cancer research, be unprepared. “The session lasted about three hours,” The Times reported, “But all work and no play can make for unhappy waltz partners.” So goulash and soft drinks were served during an intermission. “We had hard drinks prepared,” Ms. Waldheim said, “but we decided against it because it’s strenuous enough to waltz without that.” Photo: Jack Manning/The New York Times
