Ever wonder who invented the ionization smoke detector? David Lucht, P.E., FSPE tells you who and how in his article "Where There's Smoke" in the latest issue of NFPA Journal.
As Lucht notes, ionization smoke detection wasn’t new. But Duane Pearsall was the first to realize that the basic technology in the ion meter his engineer, Lyman Blackwell, had put together in 1963 to remove electrostatic charges in commercial and industrial applications "held the potential for a new kind of smoke detector." Over the past 50 years, Pearsall's work has had a profound influence on fire safety around the world, saving tens of thousands of lives that might otherwise have been lost to fire.
Cerberus GmbH was founded in 1941. Elektrowatt did a takeover of Cerberus in 1944. Their F1 detector was developed at that time. Pyrotronics entered into a license agreement in 1954.I didn't read the article, but 1963 is a late entry into the ionization technology that had already been sold for years. Dr. E. Meili was a driving force in the development of the ion detector in my mine. Comments?
