Roger Dajoz (22 August 1929 - 2019) was a French biologist, ecologist and entomologist, former student of the Ecole Normale Supérieure and a teacher at the Museum national d'histoire naturelle in Paris.[1] He specialised in the insects that feed on rotting wood and gave the term saproxylic insects in 1966 and has been considered the father of saproxylic entomology. Most of his writings were in French.[2]
He published a number of books on ecology, entomology and biology. One of the most important is an Ecology dictionary named Précis d'écologie, published by Dunod in French.
He married Aline Langevin, anglicist and French physicist Paul Langevin's granddaughter. They gave birth to two daughters, Isabelle Dajoz, who is a biologist and a teacher at Université Denis Diderot, and Hélène Dajoz, who is a teacher in mathematics.
