Lift was invented by:
E.G. Otis
The question asks about the individual credited with inventing the lift. A lift, also commonly known as an elevator, is a type of vertical transport equipment that efficiently moves people or goods between floors of a building, vessel, or other structure.
Early forms of lifts existed for centuries, powered by manual, hydraulic, or steam methods. However, these lacked crucial safety features.
The key development in the history of lifts that made them practical and safe for public use was the invention of a reliable safety mechanism. This mechanism prevented the elevator car from falling if the hoisting ropes failed.
Among the options provided, one name stands out in relation to this critical invention:
It was Elisha Graves Otis who developed the safety brake for elevators in the 1850s. His famous demonstration at the 1854 New York World's Fair, where he cut the hoisting rope and the platform didn't fall, proved the reliability of his invention and paved the way for the widespread adoption of passenger elevators in multi-story buildings.
Therefore, E.G. Otis is recognized for this pivotal invention in lift technology.
Based on historical records of technological advancements, the invention that revolutionized the lift and made it safe for passenger transport is attributed to E.G. Otis.

Elisha Graves Otis founded the Otis Elevator Company in 1853. His safety brake system was the critical invention that allowed for the construction of taller buildings, as people could now safely and efficiently travel to upper floors. Before the safety elevator, tall buildings were impractical because climbing many flights of stairs was tiring and time-consuming, and earlier lifts were considered too risky for passengers due to the lack of a reliable fall-prevention mechanism. The invention of the safety lift fundamentally changed urban architecture and development.
