Fabre was a popular teacherJean-Henri Casimir Fabre (1823-1915) was a French naturalist, entomologist, and author known for the lively style of his popular books on the lives of insects., physicist, chemist and botanist. However, he is probably best known for his findings in the field of entomology, the study of insects, and is considered by many to be the father of modern entomology. Much of his enduring popularity is due to his marvellous teaching ability and his manner of writing about the lives of insects in biographical form, which he preferred to a clinically detached, journalistic mode of recording.
