Secret decoders are generally circular scales, descendants of the cipher disk developed in the 15th Century by Leon Battista Alberti. Rather than the complex polyalphabetic Alberti cipher method, the decoders for children invariably use simple Caesar cipher substitutions. The most well-known example started in 1934 with the Ovaltine company's sponsored radio program Little Orphan Annie. The fan club's member's handbook included a simple substitution cipher with a resulting numeric cipher text. This was followed the next year with a membership badge or pin that included a cipher disk - enciphering the letters A-Z to numbers 1-26. Similar badges and pocket decoders continued with the Captain Midnight radio and television programs. Ovaltine and other companies that marketed early decoders to children often included "secret messages" on their radio shows aimed at children. These could be decoded for a preview of the next episode of the show. You don't need to drink gallons of Ovaltine to get your very own secret decoder.
