The story
The J-2 began in 1935 as a rounder, friendlier take on C.G. Taylor's angular Taylor Cub, with an enclosed cabin and fat Goodyear airwheel tires. Employee Walter Jamouneau reworked it while Taylor was on sick leave, and Taylor fired him for it. William Piper hired Jamouneau back and bought out Taylor's share of the company. A 1937 fire destroyed the Bradford, Pennsylvania factory, production restarted at Lock Haven, and the firm became Piper Aircraft that November. The last of 1,207 J-2s was finished in 1938 as the J-3 took over.
Some believed the J stood for Jamouneau. Historian Peter Bowers concluded it simply followed the E, F, G and H Cubs, with I skipped because it looked like the numeral 1.
Quick answers
