Anthony Stanislas Radziwill (5 August 1960 – 10 August 1999) was an American actor and socialite. He was the son of Lee Radziwill, the younger sister of Jacqueline Kennedy Onassis, and the late Stanislas Radziwill, a Polish nobleman.
Radziwill was born in London, England. He was raised in a privileged environment, attending the best schools and universities. He graduated from Brown University in 1983 with a degree in political science. After college, he began his acting career, appearing in minor roles in several television series such as Miami Vice, Quantum Leap, and The Fresh Prince of Bel-Air.
In 1993, he was cast in the television movie Jackie Bouvier Kennedy Onassis as Aristotle Onassis, playing opposite Jacqueline Bisset and Joanne Woodward. The performance earned him a 1994 Golden Globe nomination for Best Supporting Actor. He also had roles in the films The Peacemaker, Celebrity, and The Associate.
Radziwill faced numerous personal battles during his life, including being diagnosed with testicular cancer in 1997, which he eventually lost. Following his illness, he became a vocal advocate for cancer research, attending events for the cause and even releasing a book, titled Anthony: A Gift of Hope, which detailed his battle with the disease.
Radziwill was also known for his philanthropic work. He was a founding member of the Make A Wish Foundation and the Children's Defense Fund, and was a proud supporter of the Special Olympics.
Radziwill was married twice, first to Carole Radziwill, a writer and producer, and later to Carole's sister, Anna Christina. He had two children, Sonja and Anthony Radziwill, Jr.
