Nancy Sharon Kissinger, a philanthropist, socialite, and expert in international affairs, died on August 20, 2026, at the age of 92. She was best known as the second wife of Henry Kissinger, the former U.S. secretary of state and national security adviser, with whom she shared nearly five decades of partnership.

Born in Manhattan on April 13, 1934, Nancy Maginnes was the third child of Albert Maginnes, a lawyer and former professional American football player, and Agnes Maginnes (née McKinley). She grew up in White Plains, New York, and was educated at a private girls’ school before earning a history degree from Mount Holyoke College, an elite all-women’s institution in Massachusetts. She taught history for two years and pursued a master’s degree in history at the University of California, Berkeley.

Nancy met Henry Kissinger in 1964 while working as a researcher for Nelson Rockefeller, then governor of New York and a presidential candidate. At the time, Kissinger was a Harvard professor and foreign policy adviser to Rockefeller, and was finalizing a divorce from his first wife, Ann Fleischer. Over the years, Nancy and Henry grew close, eventually marrying in a discreet civil ceremony on March 30, 1974, in Arlington, Virginia, just hours after Kissinger met with Israel’s defence minister, Moshe Dayan.

Following their marriage, Nancy Kissinger quickly became visible on the diplomatic stage. Within two months she accompanied her husband on his shuttle diplomacy in the Middle East, which contributed to ending the 1973 Arab-Israeli war. She also traveled with him to Moscow for strategic arms control talks with Soviet leader Leonid Brezhnev and was present during meetings with Mao Zedong in Beijing.

Often described as Henry Kissinger's "intellectual soulmate" and "ambassadress-at-large," Nancy was recognized for her expertise in international affairs and social adeptness. Former New York mayor Michael Bloomberg called her a "powerhouse of ideas and insights" and Henry’s most trusted adviser. Kissinger himself noted in his memoirs that she served as his conscience. Colleagues described her as assertive and protective, famously intervening in 1982 at Newark airport to defend her husband from activists’ insults, an incident that led to a lawsuit which she won.

During Kissinger’s tenure as secretary of state, which extended through President Nixon’s resignation in 1974 until January 1977, Nancy accompanied him on numerous diplomatic travels and public appearances. After leaving office, the couple settled primarily in New York’s Upper East Side and became fixtures in the city’s social and philanthropic circles. Alongside Henry, who founded the consultancy Kissinger Associates in 1982, she also managed their 300-acre estate in rural Connecticut.

Though they had no children, Nancy and Henry Kissinger remained inseparable, marking milestones such as his 50th, 90th, and 100th birthdays with carefully organized celebrations. Their final major trip together was to Henry Kissinger’s birthplace in Furth, Bavaria, less than a year before his passing.

Nancy Kissinger’s life combined intellectual rigor, diplomatic engagement, and social influence, leaving a notable legacy as a partner to one of the 20th century’s most prominent statesmen.
