Thelma Catherine "Pat" Nixon (née Ryan; March 16, 1912 – June 22, 1993) was First Lady of the United States from 1969 to 1974 as the wife of Richard Nixon, the 37th U.S. president. From 1953 to 1961, she had been the second lady of the United States when her husband was Dwight D. Eisenhower's vice president. Born in Ely, Nevada, she grew up with her two brothers in Artesia, California, graduating from Excelsior Union High School in Norwalk, California, in 1929. She attended Fullerton Junior College and later the University of Southern California. She paid for her schooling by working multiple jobs, including pharmacy manager, typist, radiographer, and retail clerk. In 1940, she married lawyer Richard Nixon and they had two daughters, Tricia and Julie. Dubbed the "Nixon team", Richard and Pat Nixon campaigned together in his successful congressional campaigns of 1946 and 1948. Richard Nixon was elected vice president in 1952 alongside General Dwight D. Eisenhower, whereupon Pat became second lady. Pat Nixon did much to add substance to the role, insisting on visiting schools, orphanages, hospitals, and village markets as she undertook many missions of goodwill across the world. As first lady, Pat Nixon promoted a number of charitable causes, including volunteerism. She oversaw the collection of more than 600 pieces of historic art and furnishings for the White House, an acquisition larger than that of any other administration. She was the most traveled first lady in U.S. history, a record unsurpassed until 25 years later. She accompanied the president as the first first lady to visit China and the Soviet Union, and was the first president's wife to be officially designated a representative of the United States on her solo trips to Africa and South America, which gained her recognition as "Madame Ambassador"; she was also the first first lady to enter a combat zone. Though her husband was re-elected in a landslide victory in 1972, her tenure as first lady ended two years later, when President Nixon resigned amid the Watergate scandal. Her public appearances became increasingly rare later in life. She and her husband settled in San Clemente, California, and later moved to New Jersey. She suffered two strokes, one in 1976 and another in 1983, and was diagnosed with lung cancer in 1992. She died in 1993, aged 81.
