First German manufacturer of rockets.

Winkler quit his job at Junkers and built and flew the first liquid propellant rocket in Germany in 1931. After the failure of his HW-2 rocket he returned to his old job at Junkers, and then worked for the government Luftforschungsanstalt (Aeronautical Research Institute) during World War II. Although he designed a number of JATO units and sounding rockets, none were ever put into production.
