Pierre Macquer
Encyclopedia
Pierre-Joseph Macquer was an influential French
chemist
.
He is known for his Dictionnaire de chymie (1766). He was also involved in practical applications, to medicine and industry, such as the French development of porcelain
. He was an opponent of Lavoisier's theories. The scholar Phillipe Macquer was his brother.
In 1752 Macquer showed that the dye Prussian blue
could be decomposed into an iron salt and a new acid (which eventually was named by others, after the dye, as Prussic acid, and eventually shown to be hydrogen cyanide).
In his 1749 Elemens de Chymie Theorique, Macquer builds on Geoffroy’s 1718 affinity table, by devoting a whole chapter to the topic of chemical affinity
:
Macquer was influenced by the works of Georges-Louis Leclerc, Comte de Buffon
as well as others.
In 1768, Macquer was elected a foreign member of the Royal Swedish Academy of Sciences
