..... (or whoever it was) could have become a rich man from the residuals.
But I don't think there was such a thing for actors in 1951.
There were some screams in "She Wore a Yellow Ribbon", but those came from 2 guys, so the Wilhelm one was apparently not used.
Anyway, that is a very interesting story.. I've read in other places about Hollywood sets being re-used.
It seems this scream is famous and has a life of its own. Originally used in the movie, "Distant Drums" it has since been heard in many a famous movie like Star Wars, Raiders of the Lost Ark, Them and many more. All this from a scream of a soldier being shot by arrow in the original movie. Sound effects managers have used it quite often, who knew. The actual scream effect was one of 5 takes, the others have also been used.
