James Dewar is a Scottish chemist and physicist who is best remembered for the  Dewar flask, the insulating container which he invented to store and transport liquefied gases at very low temperatures.  In 1891, Dewar devised an industrial process to produce large quantities of liquid oxygen.  In 1889, jointly with Sir Frederick Abel (1827-1902) James Dewar invented  cordite,  (a smokeless alternative to  blackpowder).
