From wiki: "The Ferris wheel is named after George Washington Gale Ferris, Jr., who designed an 80 meter (264 feet) wheel for the World's Columbian Exposition in Chicago, Illinois in 1893. This first wheel could carry 2,160 persons at a time; The Ferris wheel was the largest attraction at the Columbian Exposition standing over 250' tall and powered by two 1000 HP steam engines. There were 36 cars each the size of a school bus that accommodated 60 people each (20 seated, 40 standing). It took 20 minutes for the wheel to make two revolutions - the first to make six stops to allow passengers to exit and enter; the 2nd a single non-stop revolution - and for that, the ticket holder paid 50 cents."
From here on out they shall be called George Washington Gale Ferris, Jr. Wheels. Nicely done Mr. Ferris.
