Hansson PyroTech was founded in 1888 by Carl Robert Hansson in Gothenburg, Sweden. In the beginning, fireworks were the basis of the business, but in the 1890s the company also became known as a skilled and reliable manufacturer of ship's signals (blue lights). The product range was extensive and by the beginning of the 1920s the company was already producing all of the types of signal then available on the market, such as parachute rockets, blue and red lights, signal guns and lifebuoy lights.
