The Ferris Wheel
Rumor is that Ferris designed the wheel while at dinner with friends in a Chicago restaurant and that it was built without a change being made to this original sketch. There is some evidence, however, that he had designed the Wheel five or six years prior to the Exposition and it is possible that he chose a quiet moment after dinner to reveal these plans.
On June 21, 1893 the wheel was open to the public. By November 6th, 1,453,611 paid admissions had been received with possibly a thousand or more free trips having been given to various important people. The gross earnings were $726,805, of which $513,403 was retained by the company, giving them a profit of $395,000. On May 11, 1906, after 13 years the Ferris wheel was blown up .
