Don Most Autographs
Don Most (born August 8, 1953) is an American actor. He is known for his role as Ralph Malph on the television series Happy Days.
Most was born to a Jewish family in Brooklyn, New York City. He lived in Flatbush, Brooklyn, New York, and graduated from Erasmus Hall High School in 1970. He attended Lehigh University for three years from 1970 to 1973, but did not graduate. Originally intending to study engineering, he changed his major to business after his first semester. He made plans during his junior year to spend the summer of 1973 in search of acting jobs in Hollywood before completing his studies at Lehigh. Instead, he landed the Ralph Malph role on his third audition and moved to California to pursue acting full-time.
Most appeared on the 113th and final filmed but never aired episode of Room 222, entitled "Jason and Big Mo", in the role of Louie, the red-headed class wisecracker. David Jolliffe had handled the role of Bernie, the red-headed class wisecracker, for all prior appearances. Room 222 aired for the last time in January 1974, just as Happy Days began, and on the same network, ABC.
