    James Dewar

    British chemist and physicist (1842–1923)

    For other people named James Dewar, see James Dewar (disambiguation).

    Sir James DewarFRS FRSE (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 was never so honoured.[2]

    Early life

    [edit]

    James Dewar was born in Kincardine, Perthshire (now in Fife) in 1842, the youngest of six boys of Ann Dewar and Thomas Dewar, a vintner.[3] He was educated at Kincardine Parish School and then Dollar Academy. His parents died when he was 15. He attended the University of Edinburgh where he studied chemistry under Lyon Playfair (later Baron Playfair), becoming Playfair's personal assistant. Dewar also studied under August Kekulé at Ghent.

    Career

    [edit]

    In 1875, Dewar was elected Jacksonian professor of natural experimental philosophy at the University of Cambridge, becoming a member of Peterhouse.[4] He became a member

    (20 Sep 1842 - 27 Mar 1923)


    Scottish chemist and physicist whose research with materials at low-temperature led him to devise the Dewar vacuum-insulated double-walled flask, now familiar as the thermos bottle. He also was a co-inventor of cordite smokeless explosive powder.


    Short biography of Sir James Dewar >>


    from The Manufacturer and Builder (1893)

    Professor Dewar communicated to the Royal Society at its meeting on Thursday, March 9, [1893] a most interesting development of his experiments upon air at very low temperatures. Our readers are already familiar with the fact that he has liquefied air at ordinary atmospheric pressure. He has now succeeded in freezing it into a clear, transparent solid.

    The precise nature of this solid is at present doubtful, and can be settled only by further research. It maybe a jelly of solid nitrogen containing liquid oxygen, much as calves’ foot jelly contains water diffused in solid gelatine, or it may be a true ice of liquid air, in which both oxygen and nitrogen exist in the solid form. The doubt arises from the fact that Professor Dewar has not been able by his utmost efforts to solidify pure oxygen, which, unlike other gases,
