Don Sandburg (born 1930) is an American writer, actor, and producer who has worked in television, most notably as producer of The Banana Splits for Hanna-Barbera as well as WGN-TV's Bozo's Circus.
Sandburg had started in television on WCPO in Cincinnati, Ohio when he was 21. He was initially a prop manager but later became production supervisor for The Paul Dixon Show. He left after a year, hoping to get work in Denver, Colorado but ended up doing a series of other jobs until returning to Cincinnati with WLW Radio and WLWT-TV in 1953, where he joined Wally Phillips and Bob Bell to produce, direct and write The Walt Phillips Show. When WLW and WLWT's executive vice president moved to WGN Radio and Television, he brought Phillips, Bell and Sandburg along.
When WGN-TV started Bozo in 1960, Sandburg was not involved with the show until after it went to an hour format as Bozo's Circus in 1961. He was approached by station management to write for the program - he already wrote material for a morning program, Breakfast With Bugs Bunny, that evolved into Ray Rayner and His Friends - but refused, suggesting instead that he be hired to appear as a character on air, offering to write material for the show at no extra charge (union pay rates for on-air talent were higher than for writing). WGN agreed, and the character Sandy the Tramp was born. Sandy was a mute clown reminiscent of silent film comedians, although Sandburg has said he primarily based the character on Harpo Marx. Eventually, Sandburg would be named the show's producer as well. By 1965, Larry Harmon added Sandburg's "Sandy" and Ray Rayner's Oliver O. Oliver to Bozo the Clown coloring books. In 1967, Sandberg appeared in local McDonald's ads as Ronald McDonald.
