The epithet arose from the vaudeville act of George Burns and his wife, Gracie Allen, It was eventually turned into a classic comic strip produced by King Features Syndicate. Although this strip was discontinued in 1935, a popular 1960s and 1970s CBS game show, Match Game, occasionally alluded to the strip by asking those watching in the studio to shout in unison, "How dumb is she?" (borrowing from a routine from The Tonight Show). Flappers of the 1920s were also sometimes likened to dumb Doras.

There, in a nutshell, is the history of Dumb Dora. Actually the comic strip was originated by Chic Young, whose later "Blondie" is much the same as his version of Dumb Dora. The syndicate then turned the strip over to Paul Fung and later to Bill Dwyer, who produced the strip with the aid of Milt Caniff.
Milt Caniff discussed this period of his life in an interview by Will Eisner that was originally published in WILL EISNER'S SPIRIT MAGAZINE issues number 34 and 35:
Paper doll of Dumb Dora herself.
