His master's voice

Mr. Melendez’s second career as the voice of Snoopy happened entirely by accident. Because Mr. Schulz would not countenance the idea of a beagle uttering English dialogue, Mr. Melendez recited gibberish into a tape recorder, speeded it up and put the result on the soundtrack.

For his decades of squeaks, squawks and grunts, Mr. Melendez received residuals to the end of his life. —NYT
