Michel Casseux, also known as "Pisseux" (1794–1869) was a Savate instructor. He is widely considered one of the pioneers of the sport, and is even credited as its inventor.
Based on streetfighting techniques he developed around 1820 "L'art de la savate". He banned certain street-fighting manners and developed a regulated system for self-defense and competition. Due to his efforts the new sport got even eligible for members of the French upper class who consequently attended his Savate gym. Casseux elaborated the first training system for Savate and his gym (or "salle") was the first official Savate dojo at all.
It was his student and successor Charles Lecour who eventually added boxing techniques to Savate and made it what is nowadays established as French Boxing.
The first person to make an attempt to systematise savate was Michel Casseux (aka) Pisseux
The very first person who attempted to make a system out of savate was Michel Casseux, who opened the first training establishment for it.
