Liquid Air and the Liquefaction of Gases/T. O’Connor Sloane,1900

Dewer was a Scottish physicist and chemist who is best known for the invention of the Dewer flask. Dewer flasks are double walled and contain a vacuum between the walls to maintain the temperature of the liquid in the flask. They would eventually be marketed under the trade name 'thermos'. He made several advances in the study of low temperatures and created a device to produce liquid oxygen.
