Gabriel Bertrand (born 17 May 1867 in Paris, died 20 June 1962 in Paris) was a French pharmacologist, biochemist and bacteriologist.

Bertrand 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 Gabriel Bertrand[1] in 1894.[2]

Bertrand's rule refers to 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.[3] In 2005, Raubenheimer et al. fed excess carbohydrates to Spodoptera littoralis and extended Bertrand's rule to macronutrients.[4]

In 1894, with Césaire Phisalix, he developed an antivenom for use against snake bites.[5]

Bertrand was made a member of the Académie Nationale de Médecine in 1931. In 1932 he became foreign member of the Royal Netherlands Academy of Arts and Sciences.[6]
