Anthony Marshall, son convicted of looting philanthropist Brooke Astor's fortune, dies at 90

NEW YORK — Anthony Marshall's trial was a lens on the lives of the famous and monied, featuring testimony from the likes of Barbara Walters and Henry Kissinger.

And it was a window into a sordid tale of greed and intergenerational strife: the son of an elderly philanthropist being accused of taking advantage of her failing mental state.

Marshall, who died Sunday, saw his aristocratic life unravel as he was convicted in 2009 of raiding the fortune of his socialite mother, Brooke Astor. Marshall was 90.

Marshall, a decorated World War II veteran who later became a diplomat and Broadway producer, died at NewYork-Presbyterian Hospital, said his attorney, Kenneth Warner. Marshall had had heart and other health problems for years.

Marshall was sentenced to one to three years in prison after he was convicted of exploiting his aged mother's slipping mind to loot her millions. Appeals delayed his incarceration for over 3 1/2 years, but Marshall ultimately went to prison in June 2013.

He was granted medical parole two months later because of debilitating illness. A parole board asked whether he had regrets about the events leading to his imprisonment.

"Well, regrets, yeah," he said, "naturally."

Astor was 105 and suffering from Alzheimer's disease when she died in 2007. Years earlier, she had been awarded the nation's highest civilian honor — the Presidential Medal of Freedom — for giving away nearly $200 million to charities and institutions.

Prosecutors said Marshall helped himself to his mother's fortune by means as simple as taking artwork off her walls and as complex as getting her to change her will to give him millions of dollars formerly destined for charity. Witnesses included Walters, Kissinger and other prominent Astor friends.

Marshall's lawyers said he had the legal power to give himself gifts with his mother's money, and he believed she wanted him to have them. Defense lawyers also argued that Astor was lucid and acting out of love when she altered her will to benefit her only child.

Jurors disagreed and found Marshall guilty of grand larceny and scheming to defraud.

Marshall didn't testify or call any witnesses. But after his conviction, he bared his personal life and enlisted such prominent supporters as Al Roker and Whoopi Goldberg in an effort to stay free.

After they divorced, Astor married stockbroker Charles Marshall, who virtually banished her son to boarding schools and summer camps, Anthony Marshall said. He took his stepfather's name nonetheless.

After Charles Marshall died, she married Vincent Astor, a scion of one of the country's first ultrarich families.

Meanwhile, Anthony Marshall joined the Marines out of high school, during World War II. He was wounded leading a platoon at Iwo Jima.

Marshall later served as ambassador in posts including Kenya, Madagascar, and Trinidad and Tobago. He wrote seven books on topics ranging from African art to U.S. zoos, and he co-produced Tony Award-winning runs of "Long Day's Journey Into Night" and "I Am My Own Wife." He was married several times.

"Tony had the tenderest of hearts, a brilliant mind and an outrageous sense of humor," his widow, Charlene, wrote in a death notice in The New York Times. She is not the mother of his twin sons, Philip and Alexander, and she stood staunchly by him during the criminal case.

Marshall stepped aside as her guardian in 2006, after his son Philip filed court papers accusing him of neglecting her. Anthony Marshall denied any mistreatment.

The family rift remained even after his death.
