About James Dewar
Sir James Dewar is undoubtedly one of the world's elite scientists in history. He was an English chemist and physicist, famously known for inventing the "Vacuum flask." He also did other profound research work in atomic and molecular spectroscopy, studying in these scientific fields for over 25 years.
Background & Education
The chemist was born in Kincardine-on-Forth, Scotland. He attended Kincardine Primary School and Dollar Academy for his fundamental and high school education. Dewar is an alumnus of the University of Edinburgh, where he read chemistry.
Career Highlights
He held the positions of a professor at the "Royal Institution of Great Britain, London (1877)" and the University of Cambridge (1875) throughout his career. In 1897, he served as the president of the "Chemical Society" and, in 1902, the leader of the UK's "Association for the Advancement of Science."
Major Invention
His name is widely mentioned in connection to the concepts of "liquefaction." Thus by 1891, he had constructed machinery for yielding liquid oxygen in large quantities at the "Royal Institution."
In 1892, while working, the idea of using a vacuum-jacketed vessel to store liquid gases was conceived in his mind. This idea led to his invention of the "Dewar flask," also known as a "Thermos" or "Vacuum flask," for which he is best known.
