In business, Astor dabbled in
railroad investment, but was outsmarted by Commodore
Cornelius Vanderbilt and forced to yield control of the original
New York Central Railroad line (from
Albany to
Buffalo) to him. His principal business interest was the vast Astor Estate real estate holdings in
New York City, which he managed profitably and parsimoniously.
Military service Astor was elected
lieutenant colonel of the 12th Regiment of the New York Militia. He resigned from the office in 1853. During the
American Civil War, Astor served as a volunteer
aide-de-camp, with the rank of colonel, to
Major General George B. McClellan (then commanding general of the U.S. Army) from November 30, 1861, to July 11, 1862. In recognition of his services during the
Peninsular Campaign, Astor was
brevetted as a
brigadier general of Volunteers in March 1865. In 1880, Astor became a companion of the New York Commandery of the
Military Order of the Loyal Legion of the United States—a military society of officers who had served in the Union armed forces. He was assigned insignia number 1909. He regarded his Civil War service as the best of his life and attended the reunions of the
Loyal Legion with zeal.
Philanthropy Astor donated objects and funds to the
Metropolitan Museum of Art (in 1887, he presented it with his wife's collection of valuable laces and left a bequest of $50,000). He and his brother presented
Trinity Church in lower Manhattan with a memorial to their father: a sculptured
reredos and
altar costing $80,000. He left a bequest of $450,000 to the
Astor Library, bringing the family benefactions to the institution to a total of about $1,500,000. He also gave generously to the
New York Cancer Hospital ($100,000 bequest), New York City's
Women's Hospital, New York City's
St. Luke's Hospital ($100,000 bequest) and the
Children's Aid Society. He took an active interest in the Astor Library beyond funding. He was treasurer of its board of trustees, and in 1879 deeded to it the three lots on which the northern wing of the present building was later constructed by him. He presented it with his collection of early books and rare manuscripts. His deeply religious wife, Charlotte, supported the newly formed Children's Aid Society and sat on the board of Women's Hospital, an institution that to her dismay refused to accept cancer patients. She persuaded her husband to donate the money ($225,000) to erect the New York Cancer Hospital's first wing, the "Astor Pavilion". For twenty years, she supported a German industrial school. From 1872 until her death, she was a manager of the Women's Hospital, besides taking an active part in the
Niobrara League to aid the Indians and in many other charities. She bequeathed $150,000 to charitable organizations. ==Personal life==
