John Wheeler Leavitt

John Wheeler Leavitt (July 3, 1790 – July 17, 1870) was a New York City businessman, founder of J. W. & R. Leavitt Company, eventually declared insolvent, and grandfather of American society portrait painter Cecilia Beaux, who frequently painted members of the family.

Leavitt ran the family-owned trading partnership, and was one of the most prominent businessmen of his age until financial reverses caused the bankruptcy of the firm. In spite of the financial reverses, Leavitt and his wife went on to help raise their granddaughter painter Beaux after her mother died shortly after she was born and her French father fled back to France.
