Key ideas
Key idea 1
A boy tests his own question
On a bare hillside in Rouergue, a small boy asks whether he sees the sun with his eyes or his mouth. Rather than accept an answer, he opens his mouth and closes his eyes, then reverses the experiment. He settles the question for himself.
That boy is Jean-Henri Fabre. His life carries him from farm childhood into teaching and the observation of insects. This early experiment introduces the habit that connects those stages: asking a direct question and watching closely enough to find an answer.

Who it’s for
This book is for readers who love nature writing and the lives of self-taught scientists. It is for anyone who has watched an ant or a wasp for ten minutes and wondered what it was doing.
What this book is
What do you see the sun with, your eyes or your mouth? A small boy on a bare hillside in Rouergue tests the question for himself. He opens his mouth and shuts his eyes, then opens his eyes and shuts his mouth, and he settles it by deduction.
The boy is Jean-Henri Fabre, and this is his life, written in 1910 by Augustin Fabre, a priest from the same corner of Aveyron. You meet a farm child, a self-taught schoolmaster, a professor driven from his post in 1870, and a hermit with a stony garden full of wasps.

A farm child discovers the sun and the grasshopper
Jean-Henri Fabre was baptized at Saint-Léons in 1823. His family was poor, so he was sent as a small child to his grandparents at Malaval, on the cold granite plateau of Rouergue. Among geese, calves and sheep, he says, his mind first woke.
His grandparents could not read, and neither gave a glance to insects. Yet the observer was already forming. One dusk he heard a jingling in the broom and thought a bird was singing. He crouched in ambush for days and caught the singer, a grasshopper. His reward was a poor meal, but he had learned by his own watching.
Augustin Fabre notes that heredity does not explain this child, for no one around him cared for such things. The taste showed itself early, in play and in patience.
Childhood wonder is a first kind of science, and it needs only time and attention.
That’s 1 of 9 key points.

Questions about The Life of Jean Henri Fabre, the Entomologist

Who was Jean-Henri Fabre?
