Henry Gurdon Marquand (April 11, 1819 – February 26, 1902) was an American financier, philanthropist and art collector known for his extensive collection.

[3] Following the death of their father in 1838, Frederick sold the business, which was then renamed Ball, Tompkins & Black, and took up real estate investment and other financial ventures, and Henry was his brother's agent.

Henry established himself as a banker on Wall Street, became Director of the Equitable Life Insurance Company, and eventually made a fortune speculating on foreign currency exchange and railroads.

The two were ultimately pushed out of their investment by Jay Gould, whose monopoly on the southwestern railroad system forced them to sell.

[2] Marquand was a member of the Provisional Committee of fifty men assembled in 1869 to establish a museum of art in New York City.

In 1883, Marquand had Hunt remodel the original interiors together with enlarging the dining room and adding the service wing.

The large red brick with limestone trim home was designed in the "French transitional" style, melding elements of Renaissance and Gothic Revival, took three years to build and was completed in 1884 to accommodate his extensive art collection.

[24] After being vacant for five years, 816 Madison Avenue, one of the adjacent homes was rented by Marquand to former President Grover Cleveland.

After his death, the house sat vacant for seven years before it was sold for $500,000 to a syndicate led by former New York State Senator George B. Agnew and torn down in April 1912.

[38] All three were replaced by one large 12-story apartment building at 11 East 68th Street, today owned by HFZ Capital Group and known as The Marquand,[36] home to many prominent people, including William H. Force, sculptor Evelyn Beatrice Longman, and Elie Hirschfeld.
