Before skyscrapers forever transformed the landscape of the modern metropolis, the conveyance that made them possible had to be created. Invented in New York in the 1850s, the elevator became an urban fact of life on both sides of the Atlantic by the early twentieth century. While it may at first glance seem a modest innovation, it had wide-ranging effects, from fundamentally restructuring building design to reinforcing social class hierarchies by moving luxury apartments to upper levels, previously the domain of the lower classes. The cramped elevator cabin itself served as a reflection of life in modern growing cities, as a space of simultaneous intimacy and anonymity, constantly in motion. In this elegant and fascinating book, Andreas Bernard explores how the appearance of this new element changed notions of verticality and urban space. Transforming such landmarks as the Waldorf-Astoria and Ritz Tower in New York, he traces how the elevator quickly took hold in large American cities while gaining much slower acceptance in European cities like Paris and Berlin. Combining technological and architectural history with the literary and cinematic, Bernard opens up new ways of looking at the elevator--as a secular confessional when stalled between floors or as a recurring space in which couples fall in love. Rising upwards through modernity, Lifted takes the reader on a compelling ride through the history of the elevator.
In 1818, seven-year-old Elisha was fascinated by farm machinery. As a young man, he tried a variety of ways to make a living, but nothing fired his imagination more than the job he found in a bed-frame factory. Soon he invented a machine that made frames four times faster than ever before. In 1852, while overseeing the construction of a new factory, he had to find a way to move heavy machinery to the second floor. He didn't trust the hoisting platform, so he invented a safety brake. It was so successful that rather than lift machine parts, Elisha decided to build "people-hoisting machines." In 1857, Elisha Otis installed his first successful passenger elevator in a five-storey department store in New York City. Before Elisha's invention, buildings were never higher than six stories. At last it was possible to build skyscrapers!
