Hofmann, Hermann

Quoted in Nier, "Emergence of Physics," p. 240. Hermann Kopp lectured at Giessen on "theoretical chemistry," which A. W. Hofmann referred to as "chemical physics."... 

My emphasis. Quoted by Michael Keas, "The Structure and Philosophy of Group Research," 111 who also quotes a letter from Hofmann to Hermann Kolbe (from a collection at the Deutsches Museum), in which Hofmann says that the entire history [Geschichte] of the ammonia type was completed in six weeks. In Keas, "The Structure and Philosophy of Group Research," 114.

SS. Hofmann, "Note" (1850). For instance, the known hydrocarbon amyl hydride (today called pentane), QoHk/ was known to boil at 30"C, while the newly discovered purported "amyl radical," C,oH, boiled at 15S°C. Why would removing a single hydrogen atom produce such a dramatic change in physical properties if "amyl" were really di-amyl, C20H22 (today called decane), on the other hand, this and other physical properties of "amyl" would make perfect sense. The data on boiling points was supplied by Hermann Kopp.

Eduard Simon established that when styrene was left to stand for a period of time, it changed into a viscous fluid, which eventually became solid he erroneously took polystyrene to be an oxidation product of styrene. In 1848, at the Royal College of Chemistry in London, August Wilhelm v. Hofmann and John Blythe established that this product had the same composition as styrene they called the polymer mety-styrene . In 1920, Hermann Staudinger determined the exact nature of the styrene polymer and named it polystyrene.
