Maurie Orodenker (né Maurice, or Morris, Harry Orodenker; 21 December 1908, Philadelphia – 8 October 1993, Philadelphia)[1] was an American journalist, music critic and advertising agency executive. In the 1940s, when working as a record reviewer on Billboard magazine, he was one of the first to use the term "rock and roll" to describe upbeat blues and swing music of the type which soon afterwards became known as "rhythm and blues".
