Louis-Jacques ThenardDied 21 Jun 1857 at age 80 (born 4 May 1777).French chemist, teacher, and author of an influential four-volume text on basic chemical theory and practice (1813-16). In 1808, he was the first to isolate the element boron in collaboration with Gay-Lussac. His independent achievements included studies of esters (1807), the discovery of hydrogen peroxide (1818), and work in organophosphorus compounds. He also produced a pigment known as Thenard's blue, which is stable at high temperatures and so can be used in porcelain. |
