• This situation held true until the late 19th century, when elevators began to appear in multistory buildings.
• The Roman architect Vitruvius reported that Archimedes built his first elevator around 236 B.C.
• 1743, Louis XV commissioned a lift to link his apartment in Versailles with that of his mistress.
• Eighty years later, the painter Thomas Horner and the architect Decimus Burton collaborated on an "ascending room" that hoisted visitors to a 37-meter-high platform
• 1853, when Elisha Graves Otis demonstrated his "safety elevator," featuring the first fail-safe means of arresting the elevator's fall should a support rope fail.
• 1857 Otis installed the first public elevator in a five-story department store in New York, and in 1861 he patented an elevator powered by steam
• Hydraulic and electric elevators eventually followed, finally obviating the need to climb endless flights of stairs in tall buildings.
• This kind of ponderous and expensive structure simply wouldn't do if tall buildings were to become cost-effective. Fortunately, a new building material - steel - solved this problem just in time
• By the late 1890s, the historic confluence of high real estate prices, the safety elevator and the introduction of the steel skeleton frame set off a national boom in erecting tall buildings. The age of skyscraper building had begun.
