Its the birthday of James Dewar, who was born in 1842 in Kincardine-on-Forth, Scotland. Dewar studied at the universities of Edinburgh and Cambridge. His research ranged over a wide range of topics in biology, chemistry and physics, but he is best known as a pioneer in low-temperature physics. He designed and built equipment that liquified and solidified gases, including hydrogen and oxygen, which had previously been considered permanently gaseous. Dewar also invented the vacuum flask - for use in determining the specific heat of palladium. He neglected to patent his invention, which was commercialized as a storage vessel for hot and cold drinks by two German glassblowers. They named the flask Thermos.
