There even more, BUT I don't think I have the room to put them all in.
Rocky Marciano is to this date the only undefeated heavyweight champion.
Warrior25bsc: What about Joe Calzaghe?
James J Jeffries, Joe Louis and Rocky Marciano ---- Louis lost to Max Schmeling in 1936 before he ever became champ and Jeffries was TKOed in the 15th round by Jack Johnson in 1910, six years after he retired the first time. Other than Marciano, I don't know of any. Rocky Marciano is the only heavyweight champion to retire UNDEAFETED, however the only 3 heavyweight champions to retire having DEFEATED all there opponents are Gene Tunney, Rocky Marciano and Lennox Lewis, whilst Lewis was defeated by McCall and Rahman, he avenged the defeat's in rematches, so hence "he defeated all his opponents".
Rocky Marciano holds the record for the longest undefeated streak by a heavyweight and for being the only world heavyweight champion to go undefeated throughout his career. This record was challenged by Larry Holmes in 1985 when Holmes went 48-0 before losing to Michael Spinks twice. Light heavyweight Dariusz Michalczewski also challenged Marciano's record when he was 48-0, but lost to Julio César González in his 49th fight. Julio César Chávez holds the record for longest win streak with eighty-eight straight until he suffered a draw in 1993. Heavyweight Brian Nielsen tied Marciano's record but lost his 50th fight against Dicky Ryan. Willie Pep, a featherweight, had a perfect 62-0 record before he was defeated once, followed by a 72-0-1 undefeated streak. Packy McFarland was a lightweight (fighting between 1904-1915) who lost his first fight and then won his next 98, though he never won the lightweight title. Heavyweight champion Gene Tunney never suffered a defeat at heavyweight and retired as champion, although he did lose one fight at light heavyweight.
It would be worth a bit as you see Rocky Marciano is the only hevy weight boxer not to loose a fight, oand to retire undefeated.
No Joe Louis did not beat Rocky Marciano, as Marciano was the first boxer to retire undefeated in the heavy weight class.

Marciano is the only heavyweight champion to retire with an undefeated record, though he is often omitted from the lists of the greatest of all time due to the realitivly low level of competition in the heavyweight division at that time...
1995
