  1. 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.

  2. 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 ...

  4. 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.

    Kekulé, a German of Czech descent, was intended by his family to become an architect, but at the University of Giessen he was lured to chemistry by the lectures of Justus von Liebig. After receiving his doctorate from Giessen, Kekulé served as a research assistant, first in France, then in Switzerland, then in England. In Paris he associated with C...

    Couper, who was a Scot educated in Glasgow, Edinburgh, Berlin, and Paris, came to chemistry from the study of philosophy and classical languages. This background probably helped him make an analogy between letters in words and carbon atoms in molecules, and focus on how carbon atoms combine with other atoms. His invention of an appropriate symbolic...

    Kekulé returned to Germany from England to begin his career as a university teacher, which took him from the University of Heidelberg, to the University of Ghent in Belgium, and finally to the University of Bonn, where he oversaw the establishment of a chemical institute. He was a good lecturer, well liked by his many students. As with several othe...

  5. 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.

  6. 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. Type. Proceedings. Information.
