He was the father of Francis PerrinFrancis Perrin ( Paris, 1901 id. 1992) was a French physicist, the son of Jean Perrin. With Frederic Joliot and his group, he established in 1939 the possibility of nuclear chain reactions and nuclear energy production. He was high-commissionner for atomi, also a physicist.
