John Jacob Astor III (June 10, 1822 – February 22, 1890) was the elder son of William Backhouse Astor, Sr. and the wealthiest member of the Astor family in his generation.

Biography

Astor studied at Columbia College and Göttingen, following which he went to Harvard Law School. During the American Civil War he served as a volunteer aide-de-camp to General George B. McClellan. For his services during the Peninsular Campaign he was brevetted brigadier general of U.S. Volunteers.

As a businessman, he dabbled in railroad investment, but was forced to yield control of the original New York Central Railroad line (from Albany to Buffalo) to Cornelius Vanderbilt. His principal business interest was of course the vast Astor Estate real estate holdings in New York City, which he managed profitably and parsimoniously.

In 1846, he married Charlotte Augusta Gibbes (c. 1825-1887) of South Carolina and in 1859 he built a home at 350 Fifth Avenue, which is today the street address of the Empire State Building. Later, he added an imposing vacation home, Beaulieu, in Newport, Rhode Island.

John Jacob Astor III had little inclination to do much in the way of charitable works beyond continuing gifts made by his ancestors to the Metropolitan Museum of Art, Trinity Church, and the Astor Library. However, his deeply religious wife had quite a different attitude. Charlotte Astor supported the newly formed Children's Aid Society and sat on the board of the Women's Hospital of New York, an institution that to her dismay refused to accept cancer patients. Deciding to do something about it, she persuaded her husband to donate the money to erect the New York Cancer Hospital's first wing, the "Astor Pavilion."

Aristocratic by inclination, he increasingly visited London in his later years, and his only child, William Waldorf Astor, would move there permanently with his family in 1891.

John Jacob Astor III died on February 22, 1890 and was interred in the Trinity Church Cemetery in Manhattan, New York.
