Who developed the Wankel engine and when?

German engineer and inventor Felix Wankel developed the Wankel engine, and experimental units were built and tested by the German firm NSU Motorenwerk AG beginning in 1956. Prototypes underwent further testing in 1957 and 1958 before Mazda licensed the technology in 1961 to develop and commercialize rotary engines for production automobiles.
