Stuyvesant Fish (June 24, 1851 - April 10, 1923) was born in New York City, the son of Hamilton Fish, and of his wife Julia Ursin Niemcewicz née Kean. He was an executive of the Illinois Central Railroad from 1887 to 1906, and as its president oversaw its period of greatest expansion. In 1906, he was removed from his position by E. H. Harriman, probably because of Fish's cooperation and participation with the state government in investigating the Mutual Life Insurance Company . Stuyvesant Fish also served on the board of directors of the National Park Bank.
His wife, Marion Groves née Anthon, known as "Mamie", was a leader in high-society and a dictator of styles among "the 400".
