Archimedes built his first lift or elevator, probably, in 236 B.C.

Elisha Otis was a latecomer. He did not invent the elevator, or even the first commercial elevator. He invented the first safety elevator in 1853, designed to prevent the fall of the cab if the cable broke.

The first reference about the elevator is located in the works of the Roman architect Vitruvius, who reported that Archimedes built his first lift or elevator, probably, in 236 B.C.. In some literary sources of later historical period lifts were mentioned as cabs, on the hemp rope and powered by hand or by animal's force. It is supposed that lifts of this type were installed in the Sinai monastery of Egypt. In the 17th century the prototypes of elevators were located in the palace buildings of England and France. In 1793 Ivan Kulibin created the elevator with the screw lifting mechanism for the Winter Palace of Saint Petersburg. In 1816 the elevator was established in the main building of sub Moscow village called Arkhangelskoye. In 1823, an "ascending room" made its debut in London.
In 1853, Elisha Otis introduced the safety elevator, which prevented the fall of the cab if the cable broke. The design of the OTIS safety is somewhat similar to one type still used today. It consists of knurled roller(s) that lock the elevator to its guides should the elevator descend at an excessive speed, which is monitored by a governor device.

On March 23, 1857 the first Otis elevator was installed at 488 Broadway in New York City. The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union building in New York began in 1853. An elevator shaft was included in the design for Cooper Union, because Cooper was utterly confident a safe passenger elevator would soon be invented; the shaft however was circular because Cooper felt it was the most efficient design. Later Otis designed a special elevator for the school. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems, followed by Schindler, Thyssen-Krupp, Kone and Fujitec.

The first electric elevator was built by Werner von Siemens in 1880. The safety and speed of electric elevators were significantly enhanced by Frank Sprague.

The development of elevators was led by the need for movement of large amounts of raw materials including coal and lumber from hillsides. The technology developed by these industries and the introduction of steel beam construction worked together to provide the need for the passenger and freight elevators we use today.

In 1874, J.W. Meaker patented a method which permitted elevator doors to open and close safely. U.S. Patent 147,853

In 1929, Clarence Conrad Crispen, with Inclinator Company of America, created the first residential elevator. Crispen also invented the first inclined stairlift.

Otis M. Elev. (1859-1914)

He was a merchant in Venice, and sought a way to escape the landlord each month, when rent was due.

His moveable box worked best, and was later sold (1902) to a New York highrise architect who made them useful for lovers, grafiti artists and lazy people.

[edit] Elevator safety
Elevators are characterized as being extremely safe. Their safety record of moving millions of passengers every day, with extremely low rate of incident, is unsurpassed by any other vehicle system, although fatalities due to malfunction[1] have been known to occur on occasion.[2] A certain number of passengers do die every year in elevator related incidents.[3] In 1998, in the United States, it was reported that of the estimated 120 billion rides per year in the approximately 600,000 elevators in the U.S., 10,000 people wound up in the emergency room.[4] because of elevator-related accidents. "Statistically, it's a safe ride", says Ray Lapierre, executive director of the Elevator Escalator Safety Foundation.[4]

Past problems with hydraulic elevators meant such elevators built prior to a code change in 1972 were subject to possible catastrophic failure. The code had previously required only single-bottom hydraulic cylinders; in the event of a breach of the cylinder, an uncontrolled fall of the elevator might result. Because it is impossible to verify the system completely without a pressurized casing (as described below), it is necessary to remove the piston to inspect it. The cost of removing the piston is such that it makes no economic sense to re-install the old cylinder, and therefore it is necessary to replace the cylinder and install a new piston.[citation needed]

In addition to the safety concerns for older hydraulic elevators, there is risk of leaking hydraulic oil into the aquifer and causing potential environmental contamination. This has led to the introduction of PVC liners (casings) around hydraulic cylinders which can be monitored for integrity.

In the past decade, recent innovations called machine room-less elevators first developed by Kone called the EcoSpace,[5] have reduced the amount of overhead machinery required (the main disadvantage of the traction elevator) are gradually making hydraulic elevators obsolete. Today, MRL elevator models include the Kone EcoSpace, Mitsubishi ELENESSA, Otis Gen2, Fujitec Talon, ThyssenKrupp ISIS 2 and the Schindler 400A models. In Hong Kong, few hydraulic elevators remain and most companies only install hydraulic elevators as a special order. While the new machine room-less have proved good for space, a few companies have experienced major problems with quality control, such as limited travel to 300 feet with 40 floors, and engineering design when it comes to maintenance and replacement parts.[

All I remember is that his name was Otis,not sure if that was his first or last name! lol
