The first reference to an elevator is in the works of the Roman architect Vitruvius , who reported that Archimedes built his first elevator , probably, in 236 B.C. In some literary sources of later historical periods , elevators were mentioned as cabs on a hemp rope and powered by hand or by animals.

It is supposed that elevators 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 an elevator with the screw lifting mechanism for the Winter Palace of Saint Petersburg .

In 1816 an elevator was established in the main building of sub Moscow village called Arkhangelskoye. In 1823, an "ascending room" made its debut in London , Henry Waterman of New York is credited with inventing the "standing rope control" for an elevator in 1850.

In 1853 ,  the safety elevator were introduced , which prevented the fall of the cab if the cable broke , This design of safety elevator is somewhat similar to one type still used today. A governor device engages knurled roller(s), locking the elevator to its guides should the elevator descend at excessive speed. demonstrated it at the New York exposition in the Crystal Palace in 1854.

On March 23, 1857 the first modern passenger elevator was installed at 488 Broadway in New York City , and 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 confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper felt it was the most efficient design , Later a special elevator for the schools was designed .

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 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 passenger and freight elevators in 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 .

As a part of Space Elevators goals , and what we have experienced from working in the field and from the feed back from our customers , we found that we need to support and educate our customers few major points about elevators around the world and inside the Kingdome of Saudi Arabia .

Elevators working mechanism are very simple , its a matter of balancing the passenger cabin and counterweight fillers over a traction machine using steel ropes , or even using a hydraulic oil pumping system to lift the passenger cabin using piston with pressed oil inside .

Elevators are totally safe and easy to use , there hasn't been one recorded accident were a passenger cabin has fails because the cables were cut with passenger inside , or even chocked because running out of air when the elevator break down , this is all Hollywood movies actions only .

There are many deferent types of elevators , please follow the below links to have a small brief about each type :
