Giving the Collection a Lift: Uncovering the Design History of the World Trade Center’s Elevators
From the outset, elevators functioned as the vital circulatory system of the World Trade Center and played a significant role in the efficient functioning of these quarter-mile high workplaces. Recently, the 9/11 Museum acquired two gifts that highlight the off-stage care that went into their design: an archive of materials related to the redesign of the WTC elevator cabs beginning in the early 1990s, and the donation of the iconic elevator call-button panels that served many of the elevator banks.
The first of these gifts comes by way of the National Elevator Cab and Door Corporation, a family-run business that began producing and installing elevator cabs in 1929. In 1991, the company was hired by the Port Authority of New York and New Jersey to remodel nearly 200 elevator cabs in World Trade Center Buildings 1, 2, 3, 4 and 5, along with those servicing the Vista Hotel (WTC3). Earning the contract was a huge achievement for this local company.
National is a full-service business and undertook all the work for the large WTC job itself, from producing designs and manufacturing the required materials to installing their products within the existing elevator shells. Harold Friedman, the company’s chairman for 50 years, considers an elevator cab to be a 5-by-6-foot room in which every detail is viewed up close by the room’s occupants; therefore, no part of the design or product could be overlooked.
By 1993, the design scheme for the WTC’s elevators had been established. It featured porcelain enamel panels with aluminum-painted divider strips, handrails resting on marble chair-rails, painted aluminum ceilings and a mirror-finished stainless-steel light cove. The wall panels would be outfitted with attached clips so they could be easily inserted into a template that then screwed onto the elevator shell wall. This made the panel installation process as efficient as possible and easily removable for the next elevator remodel. Remodels were typically undertaken once every 20 years.
