Marie Pasteur was one of the daughters of the Rector of the Strasbourg Academy. It seems that for years afterward, famous crystallographer, physicist and mathematician
Jean Baptiste Biot, Marie Pasteur, and Louis' father, Jean Joseph, cooperated in providing Louis with moral support. For instance, in a letter by Biot to Jean Joseph: "your son is ours also and we share with Marie all our love for him, too". The philosopher
Charles Chappuis was also a supporter and friend of Louis. The Pasteurs had five children, of whom two reached adulthood. ==References==
