In 1875, Mr. L.J. Wing, a Yankee inventor, founded the L.J. Wing Company with his invention of a disc fan with variable pitched blades. Mr. Wing produced many notable inventions and was recognized by the American Institute for his outstanding achievements. These include his introduction of the first steam turbine driven fan in 1905; his development of the first floor mounted steam unit heater in 1917; and also in 1917, a test on the U.S.S. Kimberly using L.J. Wing 'pressure type' fans that resulted in over 200 World War I Navy ships being fitted with those ventilation fans.
