            Junkers designed his first aircraft, with a thick-section cantilever
            wing as early as 1910.  Although it was never built, the first
            Junkers aircraft, the J1 of 1915, used the same wing
            design.  The J4 (military designation J.1) of
            1917 also included corrugated light-alloy skin--a feature that would
            distinguish Junkers products into the 1930s.
Junkers
            Flugzeugwerke concentrated on transport aircraft in the 1920s
            and early 1930s, switching to bombers and transports as the
            Luftwaffe expanded in the late 1930s.  In 1923, Junkers
            Motorenbau (Jumo) was formed.  Junkers Flugzeugwerke and
            Motorenbau merged in 1936 to form Junkers Flugzeug und
            Motorenwerke (IFM).
Probably
            the most famous Junker aircraft are the Ju 52 tri-motor
            transport, the Ju 87 Stuka dive bomber and the Ju 88
            "Schnell" bomber.
In 1945, most Junkers
            assets were in what became East Germany and disappeared into the
            Soviet Union.  What remained of Junkers in West Germany was
            privatized in 1956 and acquired by Messerschmitt
            AG in 1965.
