Located in New York City, the world's first and foremost vertical metropolis, The Skyscraper Museum celebrates the City's rich architectural heritage and examines the historical forces and individuals that have shaped its successive skylines. Through exhibitions, programs, and publications, the Museum explores tall buildings as objects of design, products of technology, sites of construction, investments in real estate, and places of work and residence.
The City Investing Company Building rose on the same block as the Singer tower and was completed the same year, when together the two represented the tallest and largest office buildings in the world.

The 315-foot iron-braced wood tower was erected for the 1853 New York World's Fair. Steam elevators accessed three observation platforms, affording panoramic views. Despite its popularity, the tower failed to pay off its debts and burned down in 1856.

Shot towers produced round bullets by dropping molten lead from a great height. In 1855, for the 175- foot McCullough Shot Tower at Centre and Pearl Streets, James Bogardus created a 8-tiered structure that carried an in-fill bruck wall entirely on the cast iron frame.

The 5-story Oriel CHambers in Liverpool by the little know architect Peter Ellis was the first British building with a metal frame and a curtain wall of enlarged glass oriel windows.

Fireproof construction became a great concern with the increasing height of buildings. This early system was published in 1870 in the Technologist shows wrought-iron floor beams enscased in concrete to protect them from heat. Non-combustible hollow tiles span between beams. Wood flooring and a plaster ceiling were placed on either side of the fireproof floor.

Located at Wall and Broad streets, the Drexel Building, headquarters to financier J.P. Morgan, became the first office building in the world illuminated by electric lights. On September 4, 1882, Thomas Edison and the Directors of the Edison Electric Illuminating Company of New York switched on lights powered by the Pearl Street generating station.

The grid of metal columns, beams, and girders that evolved into the skeleton of steel I-beams used in most 20th-century skyscrapers was largely the invention of multiple Chicago architects and engineers. The frame of the 1892 Unity Building is illustrated under construction in the book Industrial Chicago.

This code revision was the first in New York to allow for metal-skeleton frames, but required minimum thicknesses of masonry–a conservatism based on concerns about fire. Masonry curtain walls were generally allowed to be 4 inches thinner than load-bearing walls of the same height, narrowing as they rose.

At 11 stories, it was not the tallest in the city, but with a frontage on Broadway of a mere 21.5 feet, it was extremely slender for its height. The novelty of its metal-cage construction was the subject of considerable attention in the popular press, as pundits predicted its collapse.
The NYC Building Code did not explicitly allow for skeleton-frame construction until 1892, but the Department of Buildings approved Gilbert's individual application. As author and engineer Donald Friedman explains, the Tower Building had a hybrid structural system: "the side walls were bearing at the top four levels of steel framing, but were carried below that point on a frame consisting of wrought-iron beams and cast-iron columns. In other words, the Tower Building was, structurally, a four-story bearing-wall building sitting on top of a seven-story skeleton frame. The overall building was noticeably slender and the weight of the bearing-wall structure at the top probably helped the frame below perform: cast-iron columns cannot handle tension well, and the weight of the upper-floor masonry served as a pre-stressing compression load in the columns below."
