Gloria Vanderbilt, the actress, fashion designer, model and author from one of New York's most prominent families, died Monday at 95.
The cause was stomach cancer, her son, the CNN and CBS journalist Anderson Cooper, said.
In a statement Cooper called Vanderbilt "an extraordinary woman, who loved life, and lived it on her own terms [and] a remarkable mother, wife, and friend. She was 95 years old, but ask anyone close to her, and they'd tell you, she was the youngest person they knew, the coolest, and most modern."
Vanderbilt's life was filled with enormous success and equal amounts of heartbreak, as she built a designer-clothing business -- with the white-swan insignia -- and lost a son to suicide.
She was born in 1924 to Reginald Claypoole Vanderbilt, great-grandson of the railroad executive Cornelius Vanderbilt, and Gloria Morgan.
Early in life, Gloria was the focus of a dispute between her mother and aunt over her share of a trust fund that her father had left her. The press dubbed her the "Poor Little Rich Girl."
She was married four times -- including to the composer Leopold Stokowski and the film director Sidney Lumet -- and reportedly dated prominent personalities including Frank Sinatra, Marlon Brando and Howard Hughes.
Her acting career took her to Broadway (The Time of Your Life) and television (Playhouse 90). She wrote a number of books, including poetry, memoirs and novels. Prominent among them: The Rainbow Comes and Goes: A Mother and Son on Life, Loss And Love, a memoir co-written with Cooper.
