 Augustin Hamon and his wife wanted their children to be raised in the altruist culture and under anarchist principles, so they had no objections to their young daughter living with Jean Painlevé as an unmarried couple ("living in sin"), something socially unacceptable in Catholic France, and, even more so, in deeply Catholic Penvenan, where the Hamons resided.The Hamon family and their lifestyle influenced Jean Painlevé not only in his politics but in his outlook on life in general.Painlevé joined the Hamon daughters, all of whom would go on to become scientists, in their quest to acquire knowledge on everything.
