French pharmacologist, biochemist and bacteriologist, who introduced into biochemistry both the term “oxidase” and the concept of trace elements. The laccase, a polyphenol oxidase and an enzyme oxidating urishiol and laccol obtained from the lacquer tree, was first studied by Bertrand in 1894. Bertrand's rule is the fact that the dose–response curve for many micronutrients is non-monotonic, having an initial stage of increasing benefits with increased intake, followed by increasing costs as excesses become toxic. In 1894, with Césaire Phisalix, he developed an antivenom for use against snake bites. He died on 20 June 1962 in Paris, aged 95.
