Donald Earl Messick (September 7, 1926 October 24, 1997) was a famous voice actor, best known for voicing Creator/HannaBarbera characters from the late 1950s into the 1990s. Some of his most famous roles were Scooby-Doo from ''Franchise/ScoobyDoo'' (arguably the role for which he is best remembered), Bamm-Bamm Rubble from ''WesternAnimation/TheFlintstones'', and Astro from ''WesternAnimation/TheJetsons''. In 1996, Messick suffered a stroke while recording voices. He recovered, but died of a second one in 1997. A year later, ''WesternAnimation/ScoobyDooOnZombieIsland'' was released in his memory.
