In the 19th century Elisha Graves Otis introduced power elevators with safety brakes. Elevators then were powered by steam, which was a major breakthrough from the traditional manual operation. However, they were deemed unsafe due to cables that were susceptible to breakage. So Otis introduced something better: vertical lifts with brakes. Today, Elisha Graves Otis is acknowledged as the man who invented the elevator. Due to his innovations to make them fit for human use he is the first elevator inventor.
It is because of Otis that people can now be carried up skyscrapers having a hundred floors or more in a safe manner. Before this, high rise buildings had the problem of how people could get to the upper floors without using the stairs.
Other Inventors
In the year 1846 Sir William Armstrong invented the hydraulic powered crane, paving the way for hydraulic elevators. This replaced the type that was powered by steam. In 1880 Werner Von Siemens of Germany invented the electric elevator. The hydraulic and electric lifts are commonly in use today.
