This article traces the evolution

of the powered passenger elevator

from its initial development in the

mid-19th century to the installation

of the three separate elevator systems

in the Eiffel Tower in 1889. The design

of the Tower’s elevators involved

problems of capacity, length of rise,

and safety far greater than any

previously encountered in the field;

and the equipment that resulted was

the first capable of meeting the

conditions of vertical transportation

found in the just

emerging skyscraper.
