Hace 21 horas · History Pre-industrial era Elevator design by the German engineer Konrad Kyeser (1405). 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.
