Ernst Heinkel (January 24 1888 – January 30 1958) was a German aircraft designer and manufacturer.
In 1921, Heinkel was appointed head designer of the recently re-established Caspar-Werke, but soon left after a dispute over ownership of a design. In 1922 he established the Heinkel-Flugzeugwerke company at Warnemünde. Due to the restrictions placed on German aircraft manufacturing by the Treaty of Versailles, Heinkel looked overseas for contracts, with some seaplane designs being licence-built in Sweden and working on catapult-launched seaplanes for the Imperial Japanese Navy. Back in Germany, he installed a similar catapult on the ocean liner Bremen for launching mail planes.
After Adolf Hitler came to power, designs by Heinkel's firm formed a vital part of the Luftwaffe's growing strength in the years leading up to the Second World War. This included the Heinkel He 59, the Heinkel He 115 and the Heinkel He 111.
Heinkel was passionate about high-speed flight, and was keen on exploring alternative forms of aircraft propulsion. He donated aircraft to Wernher von Braun who was investigating rocket propulsion for aircraft, as well as sponsoring the research of Hans von Ohain into turbojet engines.
Heinkel had been a critic of Hitler's regime from the time that he had been forced to sack Jewish designers and staff in 1933. In 1942 the government "nationalised" the Heinkel works. In practice, this meant that Heinkel was detained until he sold his controlling interest in his factories to Hermann Göring. Heinkel moved to Vienna and started a new design bureau there, working on the Heinkel He 274 design until the war ended.
At the end of the war Heinkel was arrested by the Allies but evidence of anti-Hitler activities and his treatment by the regime led to his acquittal and he was allowed to go free, although his company (along with the rest of Germany's aviation industry) was initially forbidden to produce aircraft.
In 1956 he introduced the Heinkel Kabine, one of a number of European bubblecars. Over 5,000 were produced at two plants in Germany before production ended in 1958. Production continued under license in Argentina until 1961, but an attempt to start production in Ireland ended due to quality control problems. The Trojan Ltd company of Croydon, England,produced 6000 or so Kabine cars under licence. They produced four variants and prototypes for several more between 1961 and 1965. Their price reduced the demand in the face of cheap ordinary cars so production ceased.
