The ionization chamber smoke detector was invented in the early 1940s in Switzerland , and introduced into the U.S. in 1951.While American inventors upgraded burglary protection, Europeans improved the art of fire detection with the ionization smoke detector. The technology was invented in Nazi Germany to protect munitions plants in the late 1930s. Thereafter, Swiss scientists working for the firm Cerberus refined the German model. In the mid-1950s, Cerberus (now owned by Siemens) began marketing smoke detectors in America through the company Pyrene, which was owned by Baker Industries.Check these links:http://www.orau.org/PTP/collection/consumer%20products/smokedetector.htm
