Parker-Hannifin Corporation
A maker of motion and control technologies, Parker-Hannifin builds the hydraulic, pneumatic and filtration parts that power everything from factory machinery and aircraft to trucks and heavy equipment. Founded in 1917 as the Parker Appliance Company in Cleveland, it made its name in 1927 when its couplings linked the fuel tanks of Charles Lindbergh's Spirit of St. Louis on its famous Atlantic crossing. Its hyphenated name came from a 1957 merger with the Hannifin Corporation, another hydraulics maker.
