On July 7, 1976, at La Casa Pacifica, Nixon suffered a stroke, which resulted in the paralysis of her entire left side. Appearing "frail and slightly bent", she appeared in public for the opening of the Richard Nixon Library & Birthplace (now Richard Nixon Presidential Library and Museum) in Yorba Linda, California, on July 19, 1990. She met Richard Nixon in 1938 while both took part in a community theater production, and they married on June 21, 1940. During the Second World War she worked for the Office of Price Administration in San Francisco while Nixon served in the Navy. As Second Lady she traveled widely with Nixon on goodwill tours, and as First Lady she visited dozens of countries. In 1972 she accompanied him on the historic trip to China. At the White House she added over 600 historic items to the collection and widened public tours, including tours for blind visitors. Pat Nixon died of lung cancer at her Park Ridge, New Jersey home at 5:45 a.m. on June 22, 1993. Her daughters and husband were by her side. Lady Bird Johnson was unable to attend because she was in the hospital recovering from a stroke, and Jacqueline Kennedy Onassis did not attend either.
