When the United States entered
World War II in December 1941, the federal government required metal for use in the war effort. General Bronze Corporation began assisting in the manufacture of weapons, such as machine gun
emplacements. Upon its founding, General Bronze Corporation was one of the largest
metal fabricators in New York City.

Park Avenue at 52nd Street The
Seagram Building on
New York City's
Park Avenue remains the "iconic glass box sheathed in
bronze, designed by
Mies van der Rohe." To supply the demand for bronze required for the construction, the General Bronze Corporation fabricated 3,200,000 pounds (1,600 tons) at its plant in
Garden City, New York. Another interesting fact was that New York City's
zoning laws were reconfigured for the Seagram Building, so that
setbacks were no longer required. "This proved to be a no-setback building but a building all set back," since the entire building was set back 100 feet from Park Avenue. "Bronze was selected because of its color, both before and after aging, its
corrosion resistance, and its
extrusion properties." This produced the desired design by Mies van der Rohe. It was not only the most expensive building of its time — $36 million — but it was the first building in the world with floor-to-ceiling glass walls. General Bronze Corporation manufactured and supplied the building with 5400 individual windows, spandrel frames, louvers, and architectural metalwork since at that time it was the world's largest fabricator of aluminum and other non-ferrous metals. The land had been donated by the
Rockefeller family, the old slaughterhouse district along the
East River bordered by
First Avenue between East 41st and East 47th Streets. The
East River site for the
U.N, extending some 1500 feet from 42nd to 48th Streets, from First Avenue to the edge of the East River, had a "sufficient scale for applying the fundamental elements of modern urbanism, sunlight, and verdure. General Bronze assured that the "aluminum panels would be recessed flush with the inside faces of the huge (2-foot, 10-inch by 4-foot, 11-inch) aluminum-sheathed columns." The curtain wall consists of a 4-foot 7-inch-high, two-tone aluminum spandrel and sill panel and an 8-foot-high window of clear glass. All of the natural-finished aluminum has a matte texture, as does the narrow black-anodized aluminum sill panel. Each bay is subdivided by five extruded aluminum mullions which are spaced 4 feet, 10 inches on center concerning each other and to the structural columns." The building was constructed after a change in New York City's
building and zoning laws so that the area was large enough for
Skidmore, Owings & Merrill to accommodate the building. The political method employed was a "demapping" (literally, removing a street from the city plan) of Lower Manhattan." The building sits on a two-and-a-half-acre plot after Cedar Street was removed, "to form a superblock, bordered by Pine, Liberty, William, and Nassau Streets. The Chase Manhattan Building, the trademark for
David Rockefeller and the empire forged by his grandfather
John D. Rockefeller, rise "60 steel-ribbed stories out of the dark canyons of the financial district, the great glass and aluminum slab of the Chase Manhattan Bank stands at 813 feet, the sixth tallest building in the city and the world," in 1961. There are 2,239,530 square feet of gross floor area, and "is the largest banking operation ever assembled under one roof, costing $813 million, the largest total investment in a building of its type, and detail for detail, in overall quality as well as outright size, one of the most remarkable planning, architectural, and engineering accomplishments," at the time it was built. ==L.S.
