progression, along with that of the push-button controls were key introductory elements

controlling the elevator's destination was applied. This system was called automatic car

application in 1889. This presentation took place in one of New York's finest buildings,

In 1915, eleven years after the push-button controls, the first automatic system of

Time-Life building (1971). By this time, elevators had vastly ameliorated, but

Operated by means of a vertical plunger, this elevator traveled up and down a cylinder

if both sets of doors are shut. In nearly all buildings, elevators contain photoelectric
