Pierre Armand Jacquet

Pierre Armand Jacquet (born April 7, 1906 in St. Mande , † September 6, 1967 off the Spanish coast) was a French chemical engineer and metallurgist.

Jacquet studied at the École Normale Supérieure de Chimie in Paris with a degree as a chemical engineer in 1926 and a doctorate in 1938. He first worked in the research laboratory of the Société de Matériel Téléphonique in Paris, then in the laboratory of Frédéric Joliot-Curie , in the Second World War in industry and from 1945 for the French Navy. He was also an independent advisor to the Office National des Études et Recherches Aéronautiques (ONERA) and the Commissariat á l'Énergie Atomique (CEA). In 1966 he retired and moved to Banyuls . He died in a shipwreck off the Spanish coast.

In 1929 he developed the process of electrolytic polishing to produce very smooth metal surfaces (which he expanded to include the most common metals by 1940). In 1951 he found a method to find flaws in steel by polishing and etching at the same time and in 1957 he and E. Mencarelli developed a method to examine metal surfaces non-destructively (with a nitrocellulose varnish, which is viewed under the electron microscope after peeling off). He also dealt with various other metallurgy issues and published about 200 scientific papers. In 1960 he was elected to the American Academy of Arts and Sciences .
