DeWitt Clinton Clobber (his full name) was conceived by producer Gene Deitch (Gerald McBoing-Boing, Ter'ble Thompson) as a somewhat more subtle character than what the studio had typically done before, such as Heckle and Jeckle He was a humanoid character, the superintendent of a run-down old New York apartment building, with all the callousness and bad attitude typical of the position. And yet, he was pretty soft and sensitive on the inside, at least when nobody was watching. He showed true tenderness, especially, for the decrepit, disreputable building he cared for, The Flamboyant Arms, and for his job of caring for it.
Deitch later said one of the factors inspiring Clint was a desire to find a new character for Doug Moye to voice. Moye, a cameraman for the studio, had a big, booming voice that had gotten laughs as The Terry Bear's Papa, and Deitch had decided to retire those characters. But funny as his voice had been in the earlier role, he wasn't a professional actor, and this one, Deitch decided, called for professional acting. Deitch brought in Allen Swift (Tooter Turtle, Simon Bar Sinister) for the role in the majority of Clint's cartoons.
Clint Clobber was strictly a product of the 1950s. The first of his seven cartoons, Clint Clobber's Cat, was released during July, 1957. The last, The Flamboyant Arms, came out during April, 1959.
