After being awarded the contract to build the tower, Eiffel discovered that the Exposition Committee would only grant about a fourth of the monies needed to construct it. Eiffel himself would have to finance the balance. He struck a deal that would make him a very rich man. He agreed to independently find the funders for his tower but he wanted sole control of the tower and its profits for twenty years. They agreed. In a surprise to everyone, including Eiffel, the tower was paid off in the first year.
