CoffeeGeekI've done a ton of historical research into siphon coffee makers over the past decade, and have documented most of the history of siphons in the USA.
For instance, here's the original patent for the first siphon coffee maker designed and sold in the USA: the original Silex Siphon patent from 1914; this is pre Corning Pyrex, which came a year later.
