A platform for research: civil engineering, architecture and urbanism
It is not the writer’s intention to describe the multitude of details used in passenger elevator practice, but to outline the steps of their general evolution, and the results attained, or sought to be attained, in the effort to improve their efficiency, service and safety. Until the advent of the first steam passenger elevator, nearly half a century ago, buildings were limited to a few stories, and, while this type of elevator stimulated increased height, its operation was too slow to create a very marked effect, and it was not until the hydraulic elevator was introduced that much increase in the height of buildings was noticeable.
