Archibald Scott Couper


Scottish chemist who proposed an early theory of chemical structure and bonding. He developed the concepts of tetravalent carbon atoms linking together to form large molecules, and that the bonding order of the atoms in a molecule can be determined from chemical evidence.

Couper published his "New Chemical Theory" in French in a condensed form on 14 June 1858, then in detailed papers simultaneously in French and English in August 1858. Couper's idea that carbon atoms can link to each other following valence regularities was independent of a paper by August Kekulé proposing the same concept. (Kekulé had already proposed the tetravalence of carbon in 1857.)

In May 1859 he suffered a nervous breakdown, and entered an institution as a private patient. Released in July 1859, he almost immediately suffered a relapse—it was said to have been from sunstroke—and was treated again until November 1862. But his health was now broken, and he did no more serious work, spending the last 30 years of his life in the care of his mother. He died on 11 March 1892 at age 60 in Kirkintilloch.
