GENERAL KNOWLEDGE

Detailed explanation-1: -The first human-powered, counter-weighted, personal elevator was built in 1743 for King Louis XV of France. It connected his apartment in Versailles to that of his mistress, Madame de Chateauroux, who lived one floor above him. Elevator technology began to advance significantly in the 19th century.

Detailed explanation-2: -The first one was built by the German inventor Werner von Siemens in 1880.

Detailed explanation-3: -The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes (c. 287 BC – c. 212 BC) built his first elevator probably in 236 BC. Sources from later periods mention elevators as cabs on a hemp rope, powered by people or animals.

Detailed explanation-4: -Elevators, just like many other advances in technology, became far more common in the mid-1800s during the Industrial Revolution. Many of these elevators were based off the hydraulic system, in which a piston inside a cylinder used pressure from water or oil to raise or lower the elevator car.
