Answer
Siemens's contribution to elevators was the invention of the electric elevator. Before Siemens's innovation, elevators were powered by steam or hydraulics, which limited their height and speed. Siemens's electric elevator, introduced in 1880, used an electric motor to drive a winding drum that lifted the elevator car. This design allowed for taller and faster elevators, revolutionizing the construction of high-rise buildings.
