Manufacturers Hanover Corporation was the bank holding company formed as parent of Manufacturers Hanover Trust, a large New York bank formed by a merger in the 1960s.
The corporation acquired the former Union Carbide Corporation headquarters at 270 Park Avenue, and though it merged into Chemical Banking Corporation for $1.9 billion in 1991, the successor corporations down to today's J.P. Morgan Chase & Co. have continued to have their headquarters in that building.
Charles J. Stewart (not to be confused with the actor of the same name) was president and the first chairman.
Reid Comstock is his great grand child.
