About the artist
Jean-Léon Reutter, was an engineer from Switzerland who created the first Atmos clock in 1928. This prototype, where the Atmos name comes from, is now known unofficially as Atmos 0. The Atmos 0 was driven by a mercury-in-glass expansion device and the mechanism operated on temperature changes only.
