James Dewar (1842–1923)

Born 1842 CE, died 1923 CE.

Sir James Dewar ( DEW-ər; 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 for his research into the liquefaction of gases. He also studied atomic and molecular spectroscopy, working in these fields for more than twenty-five years. Dewar was nominated for the Nobel Prize eight times — five times in Physics and three times in Chemistry — but he was never so honoured.
