The Infrastructure of a Name

Every single day. Some PhD student in some university leans over a £2 million NMR. Some undergrad in Africa troubleshoot a 30-year-old UV-Vis. Some pharma chemist in Basel runs QC. At 10am, 2pm, 7pm—someone, somewhere, puts a pyrido[1,2-a]pyrimidine derivative in a cuvette. They run the scan. They get two bands: ∼240 mμ and ∼315 mμ. They write the numbers in their notebook. They don’t cite anyone. They think it’s “just Beer-Lambert.” They don’t know that in 1958, a man measured eight compounds by hand and defined the spectroscopy of this compound, wrote: “The absorption band at 315 mμ can be ascribed to the 2-imino-1-substituted-1,2-dihydropyridine chromophore.” They are using his numbers, but they never knew his name...no institution. In 1983, Hermecz & Mészáros proved the weight of those numbers. They took Antaki’s 1962 assignments and built the entire spectroscopic foundation of Advances in Heterocyclic Chemistry Vol. 33 upon them. It became the canonical review. Every chemist who has consulted that chapter since has relied on Antaki’s interpretation—whether they realize it or not. His own words: "This may be considered as evidence for the major contribution of zwitterionic fully aromatic structures such as VIII to the resonance state of the molecule." H.Antaki JAC 1958. That is the truest form of immortality in science. Not a Wikipedia entry. Not a bronze statue. Usage. There is a cruel and beautiful truth here: Lambert-Beer gave us the law (A=ϵcl), but Antaki gave us the map. 315 mμ is the 2-imino chromophore. 242 mμ is the 4-oxo chromophore. Every day, thousands of people use the Law and think that is where the story ends. They use the Map and don't even know the Map exists. He became infrastructure. He is like the 13 C NMR chemical shift of CDCl 3 ​ at 77 ppm. Who measured that first? Nobody cites it. Everyone uses it. Those two papers—1958 J. Am. Chem. Soc. 80, 3066–3068 and 1962 J. Org. Chem. 27, 1371–1374—are living inside the instruments. They are in the software baseline corrections. They are in the technician’s subconscious expectation of a band at 315 mμ. The spectrophotometer has already cited him. It does so every time the screen flashes: “Measurement Complete.”

Getting into USA!

A few pleasant days in Mexico with R, a colleague and friend for many years, attending an Exhibition.

An amazing experience compared to the Frankfurt version, the show only starts at 14:00 and lasts for a few hours, against the long hours of Frankfurt.


The exhibition went so quickly between the few meetings we had and watching all this dancing on every stand. It is just amazing to see people sitting discussing business and suddenly a stand starts a nice music and you get everyone on their feet dancing for few minutes. The same chap shouting and negotiating prices is simply transformed...beautiful exico.

A pleasant adios night out dining right after the show in a beautiful Mexican restaurant with local music and dance invited by a friend G. More Tequila and he became very emotional:

-Charles, you are my brother! ................No...............more, you are not any more Charles and I am G, you are G and I am Charles!
And as to prove his point, he took out his exhibition badge that we still had on our lapels, put it on me, and took mine for himself... He became Charles and I am G.
