Alexandre Gustave Eiffel né Bönickhausen is famous for designing the Eiffel Tower.
But Eiffel wasn’t content with simply designing one of the world’s most visited landmarks; he continued to find ways to use it.
After retiring as an architect, Eiffel built a wind tunnel at the base of the tower for his aerodynamic research, had meteorological equipment placed on various parts of the tower and suggested that the military install radio equipment on top.
In the years after Eiffel’s death, the tower continued to serve as a permanent radio tower and, eventually, for television broadcasting.
The lesson: Even your best ideas can be improved upon.
