Cannizzaro, Stanislao (1826–1910)
Italian chemist who discovered the Cannizzaro reaction in which benzaldehyde
is converted to benzyl alcohol and
benzoic acid (1853), but he is chiefly
remembered for the republication of Avogadro's
hypothesis at the Karlsruhe conference of 1860. This at last allowed chemists
to distinguish between equivalent
weights and atomic weights (see relative
atomic mass). Related category
