Nancy Kissinger, the glamorous Washington insider who spent nearly five decades at the side of former Secretary of State Henry Kissinger, has died at 92.

The philanthropist and longtime socialite died Thursday at her home in South Kent, Connecticut, according to her family, The New York Times reported.

Her death comes less than three years after Henry Kissinger died at age 100 in November 2023.

Born Nancy Maginnes in Manhattan in 1934 and raised in White Plains, New York, Kissinger built an impressive political résumé long before becoming one half of one of Washington’s most famous power couples.

She worked as an aide to New York Gov. Nelson Rockefeller and previously served as a researcher for Henry Kissinger while he was at Harvard University.

She later became a foreign policy specialist for Rockefeller’s Commission on Critical Choices for Americans.

Nancy and Henry married in 1974, while he was serving as secretary of state under President Gerald Ford.

From there, she found herself at the center of American diplomacy, frequently traveling alongside her husband during high-level missions around the world.

After Henry Kissinger left government in 1977, the couple remained major figures on the Washington social scene, regularly appearing at state dinners, embassy parties and Republican White House events.

The Times once described Nancy as an “ash-blond, chain-smoking” woman who stood nearly six feet tall — noticeably taller than her 5-foot-8 husband.

Despite their physical contrast, friends reportedly described the pair as deeply compatible and virtually inseparable.

But Nancy Kissinger was also known for having a fierce side.

That became dramatically clear during a bizarre 1982 confrontation at Newark International Airport.

According to witnesses, Ellen Kaplan, a follower of controversial political extremist Lyndon LaRouche, approached the couple and began insulting them.

Nancy allegedly responded by grabbing Kaplan by the throat and threatening to throttle her — an incident that became one of the most notorious stories surrounding the otherwise polished Washington socialite.

Nancy and Henry Kissinger had no children together.

She is survived by Henry’s two children from his first marriage, Elizabeth Vandermark and David Kissinger, as well as five step-grandchildren.

Her death closes another chapter in the story of a couple who spent decades moving through the highest levels of American political power.
