Philanthropist and wife of former Secretary of State Henry Kissinger, Nancy Kissinger, has died at age 92. This was reported by Qazaqyia.kz citing Associated Press.

Nancy Kissinger died Thursday at her home in Kent, Connecticut. According to property manager Robert Johnson, she will be buried next to her late husband at Arlington National Cemetery at a later date. The cause of death was not disclosed.

The daughter of a New York City lawyer, she met Henry Kissinger while working for New York Gov. Nelson Rockefeller. The couple wed in 1974.

She was described by one profiler as a brainy, Blass-bedecked blonde. She was often seen at high fashion openings and was a strong presence on the New York philanthropy scene.

Philanthropist Judy Peabody said after chairing a successful hospital charity event in 1989: "Nancy Kissinger can pick up the phone and get right through to the CEO. Nobody keeps her waiting."

Michael Bloomberg, the billionaire founder of the Bloomberg financial-news empire, former New York City mayor and a friend of the Kissingers, said in a social media post that Nancy Kissinger "was a powerhouse of ideas and insights that she put to work throughout her life in government and philanthropy — and as Henry's most valued and trusted advisor."

He added, "She was the ultimate diplomat — as wise as she was discreet — and I know how completely Henry admired and loved her. Diana and I were fortunate to call her a dear friend, and to see their extraordinary partnership in action over the decades. We will miss her greatly."

Nancy Kissinger made headlines in 1982 when she tried to throttle a woman who harassed her and her husband with insulting questions at Newark Airport. The couple was going to Boston, where Henry Kissinger was to undergo bypass surgery.

The woman, a leafleter for a group affiliated with politician Lyndon LaRouche, accused Nancy Kissinger of choking both her throat and her free-speech rights. Nancy Kissinger said she only wanted to protect her husband from upset.

A judge acquitted Nancy Kissinger.
