The accredited inventor of the modern elevator is Elisha Otis, who in 1852, designed his elevator system. In 1854 he staged an astonishing demonstration at the Crystal palace exhibition, where he ordered an assistant to cut the rope!
This emphatically demonstrated the safety of his emergency control system, and from that time, the world considered it safe to build skyscrapers.
I find no reference to a J Cooper.
The concept of practical small elevator was known from 200 BCE, but they were primitive machines.
There was a Peter Cooper of New York (one time Presidential candidate, and successful businessman) who built a Cooper Union Building in New york in 1853, and in its design included an elevator shaft, confident that these machines would soon be of safe design. This shaft was circular, but Otis was able to rise to the design challenge. He was the son of a J Cooper.
There are on Google some references to a J Cooper, listed as African-American who invented an "elevator device", but whether this was a building accessory, or a shoe accessory, or an orthopedic device is not listed.
In any event, the date for this reference is 1895, well after Otis.
Good hunting!

What is elevator in microcontroller?
An elevator is an electronic device that transports people or goods in a vertical motion. A microcontroller embedded in the control system of an elevator is used to control the elevator's mechanisms.

What was the importance of Thomas Edison's work?
Thomas Edison is the one who invented electricity. So without him, you probably wouldn't be on this computer device right now.
When were speed cameras invented?
They were invented in the 1950s by Maurice Gatsonides. He was a Dutch racing car (rally) driver who invented the camera so he could check his cornering during races. It was later adopted by police forces around the world. His company, Gatsometer BV, founded in 1958 made and sold the device, called a "Gatso".
Who invented the elevator device?
Elisha Otis invented the elevator in 1854.
Who invented the elvator and when was it invented?
In 1852, Elisha Otis invented a freight elevator equipped with a safety device to prevent falling in case the supporting cable would break.

When were elevators invented?
In the 3rd century BCElevators were used as far back as the 3rd century BC using human or animal power.In the 1800's steam and water power elevators were in wide use, but were hazardous.In 1853 Elisha Otis invented the safety break.The first electric elevator was built in 1880 by a German, Werner von Siemens.Note that these two names (Otis and Siemens) are still associated with elevators.The first reference about the elevator is located 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 period elevators were mentioned as cabs, on the hemp rope and powered by hand or by animal's force. 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 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. [2] Henry Waterman, of New York, invented the elevator in 1850. He intended it to transport barrels of flour. 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 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. 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 confident that a safe passenger elevator would soon be invented. The shaft 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. 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 From Wikipedia

How much did it cost Elisha Otis to invent the first elevator?
Here is what I could find on the subject: "Elisha Otis invented the "Improvement in Hoisting Apparatus." Elisha Otis didn't actually invent the elevator, he invented the brake used in modern elevators. His brakes made skyscrapers a practical reality. (above illustration - patent drawing of the Elisha Otis elevator) " What he did was invent a device that would stop the elevator if the main lifting cable broke.

What did Elisha Otis invent?
Elisha Otis is known for building the first modern passenger elevator which used his invention of a safety device which prevented the car from falling if the cables broke. The elevator safety brake was first demonstrated at the Crystal Palace Exposition in New York in 1854. After ascending in his new elevator, Otis called for the elevator's cable to be cut with an axe. Instead of falling, the elevator platform held, secured by a brake using toothed guiderails in the elevator shaft and a spring-loaded bar that automatically caught in the toothed rail of the elevator car if the cable failed. Today, the Otis Elevator Company is the world's largest company in the manufacture and service of elevators, escalators, moving walks and people-moving equipment.

What calculating device was invented by the Chinese over 5000 years ago?
Abacus was the first calculating device invented by the Chinese.
What invention by Elisha Otis in1854 made it easier to live in skyscrapers?
Elisha Otis in the early 1850's invented the first elevator with a brake that could lift and lower cargo and people safely. The safety device prevented falling in the event a supporting cable breaks. It was Otis' invention of the elevator brake that would eventually make living in skyscrapers possible.
