[1] Nevertheless, Barbier’s contributions to the scientific community were plentiful and varied, including work in mineralogy, natural products isolation, and polycyclic aromatic hydrocarbons.
He also discovered novel reactivity of aromatic hydrocarbons such as stilbene and phenanthrene, providing valuable knowledge about the constitution of coal tar and the useful components therein.
The École Supérieure de Pharmacy, with Berthelot at the head of his committee, awarded him the degree of Pharmacist, First Class.
Finally, he was rehired at the Faculte des Sciences de Lyon as professor of chemistry, where he would remain for the remainder of his career.
Considering that both Grignard and Barbier reported their individual findings as being novel (and that they published separately on the topic), it is difficult to assign credit to one person or the other for the original idea.
[10] Additionally, in line with Grignard’s statements about the unfairness of the Nobel award he received, he continued to defend Barbier’s contribution to the state of the art (though he claims his input was equally valuable), even taking care to speak with utmost fondness about his “revered master” in a biography written by his son, Robert Grignard.
[9] Barbier did, despite destroying his curriculum vitae and all other evidence of his life, eventually spoke with even tones on the matter, saying publicly, “Grignard has pointed out the rightful share that is due him in a discovery of this kind”.
He did not hesitate to sacrifice for what he regarded as the truth, and he was one of the ardent pioneers who, by demonstrating through their teaching and their researches all the power of atomic theory, contributed so effectively to forming the present generation of French chemists.”The "major power" referred to here is Barbier's own mentor, Berthelot, whose "autocratic influence"[9] over French chemical education made Barbier's insightful stance on the matter even more impressive.
[20] When the US Department of the Interior published their geological survey in 1912, they recommended that this new form of monoclinic soda feldspar should henceforth be called "barbierite".
