Henry Baubigny (1842-1913) was a French chemist who studied in detail the conversion between camphor and borneol and the preparation and properties of their derivatives (oxygenated and non-oxygenated). As a result, he synthesized a series of new compounds, such as camphor ethylide and its series, acetyl, methyl, ethyl and amyl camphor, campholic acid, camphocarbonic acid, camphic acid, etc. He also investigated the transformation of amines into amides by the reaction between a primary or secondary amine with a compound ester. Together with Lauth they developed a very cheap process for preparing the dye magenta. Baubigny used an improved sulfate procedure for determining the equivalent value of copper, zinc, nickel, aluminum, and chromium. Together with Péchard he studied the phenomenon of efflorescence and found that the result of the phenomenon varied if the hydrate had been crystallized from a neutral or an acid medium. Baubigny also studied the synthesis and properties of dithionates, as well as methods for the quantitative analysis of mixtures of halogens.
