Stanislao Cannizzaro

Born 13 Jul 1826; died 10 May 1910 at age 83. Italian chemist, teacher, and legislator who recognized the distinction between atomic and molecular weights. He discovered the Cannizzaro reaction in 1853, that treatment of benzaldehyde with a concentrated alcoholic hydroxide produced equal amounts of benzyl alcohol and the salt of benzoic acid. Earlier, in 1851, he helped prepare cyanamide, while at the laboratory of Michel-Eugène Chevreul. In 1858, he showed that the atomic weights of the elements in the molecules of a volatile compound can be calculated using Avogadro's principle. Further, the atomic weights of non-volatile compounds can be calculated by a measurement of specific heat instead of vapour density. Later, 1861-71, he studied aromatic compounds and amines.
