Named fighters KO'd in 1

Emile Griffith, ny Reuben Carter, just days before he appeared to accept "Fighter of the Year" honors in Pittsburh, leading to his classic line "Something funny happened to me on the way to Pittsburgh..."
Lots of great fighters got ko'd early, early in their careers. Benny Leonard (ko3), Henry Armstrong (ko3) and Alexis Argeullo (ko2) come to mind. I know there are many more Hall of Famers that had one round ko losses but I don't have my book and my memory fails me
No, Archie Moore got ko'd in one as well. So did the man he won the title from, Billy Miske.

I would have thought that the Max Schmelling KO1 by Joe Louis was the most famous of all time after what happened to Joe in their first fight and the huge crowd in attendance.
I know that Anthony Mundine's old man Tony Mundine had his lights turned out in 52 seconds by Luis Rodriguez in 1970. Mundine went onto beat Emile Griffith and fight Carlos Monzon for the Middleweight title and was no chump.
