Inspirational Quotes by James Dewar (Scottish Scientist)

Sir James Dewar (1842–1923) was a Scottish chemist and physicist known for advancements in cryogenics and spectroscopy. He invented the vacuum flask, essential in scientific research and later adapted into the common thermos bottle.

Born in Kincardine-on-Forth, he studied chemistry at the University of Edinburgh under Lyon Playfair. He later became a professor at the University of Cambridge (1875) and the Royal Institution of Great Britain (1877,) holding both positions throughout his career. His research on low-temperature phenomena led to the liquefaction of gases such as oxygen and hydrogen.

In 1892, Dewar developed the vacuum-jacketed vessel, now called the Dewar flask, for storing liquefied gases efficiently. He was the first to liquefy hydrogen (1898) and solidify it (1899,) advancing studies in extreme cold. His discovery that cooled charcoal aids in creating high vacuums (1905) later proved valuable in atomic physics.

Dewar collaborated with Sir Frederick Augustus Abel to develop cordite, a smokeless explosive. His contributions earned him numerous honors, including the Copley Medal (1916.) His publications include The Liquefaction of Gases (1899,) detailing his experiments, and Researches in High Vacua (1905,) examining vacuum technology. Despite multiple nominations, he never received the Nobel Prize.
