Epilogue In 1900, after the customary 11 -year period, Paris again prepared for an international exposition, about 5 years too early to take advantage of the great prog- ress made by the electric elevator. When the Roux machines, the weakest element in the Eiffel Tower system, were replaced at this time, it was by other hydraulics. Built by the well known French en- gineering organization of Fives-Lilies, the new ma- chines were the ultimate in power, control, and general excellence of operation. As in the Otis system, the cars ran all the way to the second platform. The Fives-Lilies equipment reflected the advance of European elevator engineering in this short time. The machines were rope-geared and incorporated the elegant feature of self-leveling cabins which com- pensated for the varying track inclination. For the 1900 fair, the Otis elevator in the south pier was also removed and a wide stairway to the first platform built in its place. In 1912, 25 years after Backmann's startling proposal to use electricity for his system, the remaining Otis elevator was replaced by a small electric one. This innovation was reluctantly intro- duced solely for the purpose of accommodating visitors in the \vinter when the hydraulic systems were shut PAPER 19: ELEVATOR SYSTEMS OF THE EIFFEL TOWER 39.
