## Historical Note on Faà di Bruno's Formula

While Faà di Bruno's Formula was named after Francesco Faà di Bruno, he was not the first to state it.

That honour belongs to Louis François Antoine Arbogast who published it in his textbook of $1800$ Du Calcul des Dérivations.

Faà di Bruno himself published this result in Barnaba Tortolini's magazine Annali di Scienze Matematiche e Fisiche in $1855$, and again in The Quarterly Journal of Pure and Applied Mathematics in $1857$.
