Mervyn Edward Griffin Jr. (July 6, 1925 – August 12, 2007) was an American television show host and media mogul.[2] He began his career as a radio and big band singer, later appearing in film and on Broadway.

Griffin created and produced the successful television game show Jeopardy! in 1964. Griffin wrote the 30-second piece of music heard during the show's Final Jeopardy! Round, which became the iconic melody of the theme for the syndicated version of the show hosted by Alex Trebek in 1984.
