Mid 17th century: invented by J. B. van Helmont (1577–1644), Belgian chemist, to denote an occult principle which he believed to exist in all matter; suggested by Greek khaos 'chaos', with Dutch g representing Greek kh.

  • Gas is an invented word, coined in the 17th century by the Belgian chemist and physician Joannes Baptista van Helmont (1577–1644), who was the first scientist to realize that there are gases other than air, and who discovered carbon dioxide. Van Helmont based the word on Greek khaos, chaos. It did not really catch on until the 19th century, with earlier scientists like Robert Boyle preferring to think of gases as different types of air. Gas for lighting or heating purposes dates from the late 18th century. The first experiments using coal-gas for lighting are said to have been made by the rector of Crofton, Dr Clayton, in about 1688; gas-lighting in its practical application was due to William Murdock (1754–1839).
