Back in ancient times the Greeks, Romans, and Egyptians all had an early type of elevator but they were not used very much because the rope could snap and then you plummet to your death which nobody likes to do very much on a regular basis. Very big ones to lift lumber and water out of wells but no one trusted it enough to use it for people and especially not in apartment buildings where people routinely go up and down to their apartments. Elisha Otis was the cousin of the inventor William Otis But the coal and lumber industries used who invented the steam shovel. He moved to a river and opened a grist mill using a water wheel powered by the river so he opened his own business but it failed since he didn’t get enough business. He went to go work at a saw mill and was picking up wood scraps from the day when he was thinking about a more efficient way to haul the scraps up without spilling down the stairs as he carried them up, then he thought about the small elevators the mill had but they had a bad track record so he built the safety elevator. The safety elevator has hooks in it that get pulled into the elevator when the rope pulls on it but if the rope snaps its hooks are no longer being pulled on so they will shoot out of the elevator because of springs and latch onto the hooks on the side the shaft.
