Prince Anthony Stanisà Âaw Albert Radziwià Âà  (; August 4, 1959 â August 10, 1999) was a Swiss-born American television executive and filmmaker.
He was the son of Caroline Lee Bouvier Canfield and Polish aristocrat and diplomat Prince Stanisà Âaw Radziwià Âà Â, and a nephew of former First Lady Jacqueline Kennedy Onassis.
Born in Lausanne, Switzerland, Radziwià Âà  was the son of Prince Stanisà Âaw Albrecht Radziwià Âà  by his third wife, socialite and actress Caroline Bouvier (younger sister of First Lady Jacqueline Bouvier Kennedy). By birth, he was a member of the House of Radziwill, one of the wealthiest and most important Polish-Lithuanian magnate families. He was also a descendant of King Frederick William I of Prussia via Princess Louise of Prussia, and George I of Great Britain via his only daughter Sophia Dorothea of Hanover. His paternal cousin was Countess Isabella Potocka who married Count Hubert d'Ornano, the owner of Sisley who was a son of Guillaume d'Ornano, a co-founder of Lancôme. His maternal first cousin once removed was Mary Lee Ryan (1931âÂÂ2017), the wife of William Amherst Vanderbilt Cecil, owner of Biltmore. He married a former ABC colleague, Emmy AwardâÂÂwinning journalist Carole DiFalco, on 27 August 1994 on Long Island, New York.
Radziwià Âà  attended Millfield School and Choate Rosemary Hall preparatory school in Wallingford, Connecticut. In 1982, he finished his studies at Boston University, earning a bachelor's degree in broadcast journalism. In New York, he was a member of the Knickerbocker Club.
Radziwià Âà Â's career began at NBC Sports, as an associate producer. During the 1988 Winter Olympics in Calgary, Alberta, Canada, he contributed Emmy Award-winning work. In 1989, he joined ABC News as a television producer for Primetime Live. In 1990, he won the Peabody Award for an investigation on the resurgence of Nazism in the United States. Posthumously, in 2000, Cancer: Evolution to Revolution was awarded a Peabody. His work was nominated for two Emmy's: Outstanding non-fiction special for Lenny Bruce: Swear To Tell The Truth in 1999 and Outstanding achievement in non-fiction programming for Cancer: Evolution to Revolution in 2000
Around 1989 he was diagnosed with testicular cancer and underwent treatment which left him sterile but in apparent remission. However, shortly before his wedding, new tumors emerged. Radziwià Âà  battled metastasizing cancer throughout his five years of marriage, with his wife, Carole, serving as his primary caretaker through a succession of oncologists, hospitals, operations, and experimental treatments.
The couple lived in New York, and both Radziwià Âà  and Carole tried to maintain their careers as journalists between his bouts of hospitalization.
On September 21, 1996, Radziwià Âà  was the best man for the wedding of his best friend and cousin John F. Kennedy Jr. and Carolyn Bessette. Kennedy's older sister, Caroline, was the matron of honor.
Radziwià Âà  died of cancer on August 10, 1999, six days after his 40th birthday, and less than a month after his cousin John Jr., his wife Carolyn Bessette, and her sister Lauren Bessette predeceased him in a plane crash. He was survived by his wife, his mother, his sister Tina, and his older half brother, John.
In 2000, his mother, Lee Radziwià Âà Â, and widow, Carole Radziwià Âà Â, set up a fund in his name to help emerging documentary filmmakers.
Radziwill is portrayed by Erich Bergen in Ryan Murphy's 2026 series Love Story.
