Felix Wankel

[1] Wankel was born in 1902 in Lahr in what was then the Grand Duchy of Baden in the Upper Rhine Plain of present-day southwestern Germany.

He learned the trade of purchaser at the Carl Winter Press in Heidelberg and worked for the publishing house until June 1926.

[2] Wankel was gifted since childhood with an ingenious spatial imagination and became interested in the world of machines, especially combustion engines.

[3] When his high esteem for technical innovations was not widely shared among the German Youth Movement, he was offered instead the opportunity to talk about the issue of technology and education to Adolf Hitler and other leading National Socialists in 1928.

[4] In the meantime Wankel's mother, Gerty had helped founding the local chapter of the NSDAP in his hometown of Lahr.

But they soon fell out with each other, because Wankel tried to put a stronger emphasis on military training, whereas Wagner wished for the Hitler Youth to be a primarily political organization.

Wankel, who sympathized with the social-revolutionary wing of the NSDAP with Gregor Strasser, then founded his own National Socialist splinter group in Lahr and continued his attacks on Wagner.

Since the Nazis' seizure of power on 30 January 1933 had strengthened his position, Wagner had Wankel arrested and imprisoned in the Lahr jail in March 1933.

[5] A fellow native of Baden and member of Reichstag from 1933 to 1945, Keppler had been a friend of Wankel and an ardent supporter of his technological endeavors since 1927.

[6] During World War II, Wankel developed seals and rotary valves for German air force aircraft and navy torpedoes, as well as for companies such as BMW and Daimler-Benz.

[1] However, by 1951, he got funding from the Goetze AG company to furnish the new Technical Development Center in his privately owned house in Lindau on Lake Constance.

In the same year, with the KKM 250, the first practically applied rotary engine was presented in a converted NSU Prinz automobile.

In Japan, the manufacturer Mazda licensed the engine and successfully solved various problems relating to chatter marks.

In 1971 Wankel sold his share in licensing royalties for 50 million Deutschmarks (adjusted for inflation, approximately €87m in 2021) to the English conglomerate Lonrho.

Furthermore, there is an exhibition "AUTOVISION · Tradition & Forum" in Altlußheim, a permanent showing of over 80 rotary engines and many cars equipped with Wankel motors.
