Matthew Thomas "Matt" Robinson Jr. (January 1, 1937 – August 5, 2002) was an American actor, writer and television producer.  Robinson was the first actor to portray the character of Gordon Robinson on the long–running PBS children's TV program "Sesame Street".  When "Sesame Street" began in 1969, not only did Robinson play Gordon, but he also provided the voice of the puppet Roosevelt Franklin and also was one of the show's producers.  He left the show in 1971.  In later years, when producers needed a last name for the Gordon character, then played by Hal Miller and then Roscoe Orman, they used Matt's last name. James C. Mathis III (born November 28, 1974 in Brooklyn, New York) is an American actor best known for providing the voices of Black Panther, Bulldozer and King Cobra in the animated television show "". K9, occasionally written K-9, is the name of several fictional robotic canines (dogs, the name being a pun on the pronunciation of "canine") in the long-running British science fiction television series "Doctor Who", first appearing in 1977.  K9 has also been a central character in three of the series television spin-offs: the one-off "K-9 and Company" (1981), "The Sarah Jane Adventures" (2007–2011) and "K9" (2009–2010).  Although not originally intended to be a recurring character in the series, K9 was kept in the show following his first appearance because he was expected to be popular with younger audiences.  There have been at least four separate K9 units in the series, with the first two being companions of the Fourth Doctor.  Voice actor John Leeson has provided the character's voice in most of his appearances, except during Season 17 of "Doctor Who", in which David Brierley temporarily did so.  The character was created by Bob Baker and Dave Martin, to whom rights to the character still belong; consequently, Baker's spin-off series "K9", which is not BBC-produced, cannot directly reference events or characters from "Doctor Who", though it attempts to be a part of that continuity.
