The first passenger elevator was installed in the Haughwout and Company (a New York porcelain and glass dealer) building on March 23, 1857. However, isolated examples of passenger “elevators” were found between the late seventeenth century and the early nineteenth century. For example, the Jena mathematician, Erhard Weigel, had a house built around 1670 in which he installed an arrangement of pulleys to convey him from one of its seven stories to another.
