Fleming, Sir Alexander


Fleming, Sir Alexander
(6 ago. 1881 Lochfield, Ayr, Escocia–11 mar. 1955, Londres, Inglaterra).

Bacteriólogo escocés. Mientras servía en el Cuerpo Médico del Ejército Real durante la primera guerra mundial, realizó investigaciones sobre sustancias antibacterianas que no fuesen tóxicas para los seres humanos. En 1928 descubrió, sin proponérselo, la penicilina, cuando notó que un moho que contaminaba un cultivo bacteriano inhibía el crecimiento bacteriano. Compartió el Premio Nobel de 1945 con Ernst Boris Chain y Howard Walter Florey, quienes perfeccionaron el descubrimiento básico de Flemming, aislando, purificando, ensayando y produciendo penicilina en cantidades significativas.
