Archibald Scott Couper (* 31. März 1831 in Kirkintilloch, Schottland; † 11. März 1892 ebenda) war ein schottischer Chemiker, der eine frühe Theorie der chemischen Struktur und Bindung aufstellte. Er entwickelte die Vorstellung von vierwertigen Kohlenstoffatomen, die sich zu großen Molekülen zusammenschließen.
Archibald Scott Couper ( / ˈkuːpər /; 31 March 1831 – 11 March 1892) was a 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 ...

27. März 2024 · Archibald Scott Couper was a Scottish chemist who, independently of August Kekule, proposed the tetravalency of carbon and the ability of carbon atoms to bond with one another. Couper was a student at the universities of Glasgow and Paris and became an assistant at the University of Edinburgh.

Archibald Scott Couper was the first chemist to use modern structural formulae, 150 years ago. His publication of this new concept was largely ignored at the time, and even derided by his main rival August Kekulé. He died before his contribution was recognised but his memory and the importance of his work has since been revived.
In 1858 August Kekulé (1829–1896) and Archibald Scott Couper (1831–1892), two young men from different backgrounds, independently recognized that carbon atoms can link directly to one another to form carbon chains. This finding explained the very multiplicity of carbon compounds that had been puzzling chemists.
Archibald Scott Couper is one of the most singular appearances in the history of the development of Organic Chemistry in the nineteenth century. He comes on the scene at the time—the end of the ‘fifties—when the valency theory began its victorious entrance into our science.
