Sir James Dewar FRS FRSE (/djər/ DEW-ər;[1] 20 September 1842 – 27 March 1923) was a Scottish chemist and physicist. He is best known for his invention of the vacuum flask, which he used in conjunction with research into the liquefaction of gases. He also studied atomic and molecular spectroscopy, working in these fields for more than 25 years. Dewar was nominated for the Nobel Prize 8 times — 5 times in Physics and 3 times in Chemistry — but he never succeeded in winning it.[2]
