Pierre Jacques Antoine Béchamp (1816-1908), the namesake of the Béchamp reduction, was a French chemist and biologist who worked alongside and in rivalry with fellow French scientist Louis Pasteur (1822-1895). The two first clashed over the attribution of fermentation to microorganisms, then again in the attribution of pébrine to microorganisms, then later in regard to germ theory.
