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._

of man's works. It was among the most outstanding technological
achievements of an age which was itself remarkable for such achievements.
Second to the interest shown in the tower's structural aspects was the
interest in its mechanical organs. Of these, the most exceptional were the
three separate elevator systems by which the upper levels were made
accessible to the Exposition visitors. The design of t
