The invention of currywurst is attributed to Herta Heuwer in Berlin in 1949, after she obtained ketchup (or possibly Worcestershire sauce) and curry powder from British soldiers in Germany. She mixed these ingredients with other spices and poured it over grilled pork sausage. Heuwer started selling the cheap but filling snack at a street stand in the Charlottenburg district of Berlin, where it became popular with construction workers rebuilding the devastated city. She patented her sauce under the name "Chillup" in 1951. At its height the stand was selling 10,000 servings per week. She later opened a small restaurant which operated until 1974. On 30 June 2013 Heuwer's 100th birthday was celebrated with a Google Doodle.
