William Vincent Astor (November 15, 1891 – February 3, 1959) was a businessman, philanthropist, and member of the prominent Astor family.
Vincent died on February 3, 1959, of a heart attack at his apartment at 120 East End Avenue in Manhattan. Astor left all of his money to the Vincent Astor foundation and Brooke, surprising many. She continued his philanthropic work. Vincent Astor was first interred on his "Ferncliff Courts" estate ("Astor Courts") on the Hudson River near Rhinebeck, New York. When Brooke later disposed of the property he was reinterred in the Sleepy Hollow Cemetery in Sleepy Hollow, New York. Brooke is buried next to him.
His half-brother Jakey felt cheated and resentfully stated Vincent "had the legal, not the moral right to keep all the money". Jakey sued Brooke to inherit his money. He was certain that Vincent was "mentally incompetent" when signing his last will in June 1958 due to frequent smoking and alcoholism, though Brooke insisted otherwise. While Vincent was hospitalized, Brooke would often bring him liquor. Jakey accused her of using the liquor to influence the will in her favor. Jakey ended up settling for $250,000. The rest of money remained with the Vincent Astor foundation and Brooke.
