Herta Charlotte Heuwer (née Pöppel; 30 June 1913 – 3 July 1999) owned and ran a food kiosk in West Berlin.
She is frequently credited with the invention of the take-out dish that would become the world-renowned currywurst, supposedly on 4 September 1949.
The original Currywurst was a boiled sausage, fried, with a sauce of tomato paste, Worcestershire sauce, curry powder and other ingredients.
Heuwer was born in Königsberg.
In January 1951, she registered a trademark for her sauce, Chillup.Heuwer moved her business to a larger facility at Kaiser-Friedrich-Straße 59, which, during its heyday, was open day and night and employed 19 saleswomen.
On 29 June 2003, the day before what would have been her 90th birthday, a plaque was dedicated in her honor at this address.
Heuwer died in Berlin, aged 86.
On 30 June 2013, the centenary of Heuwer's birthday, was celebrated with a Google Doodle.
