Ralph Brooks(1904-1991)

Pvt. Wilhelm, Brooks' character in Investida de Bárbaros (1953), gives name to what became known as the Wilhelm scream, an especially painful-sounding cry that was used as a sound effect in several movies and TV shows during the 1950's and 1960's. It's first appearance was in a 1951 film about old Florida, Tambores Distantes (1951), and was voiced by actor Sheb Wooley, who in this film played another private, Pvt. Jessup, who is killed by an alligator.
