author
An early 20th-century writer tied to Riverbank Laboratories, she is known for a curious educational book that introduced children to codes and close observation. Her work blends reading, number practice, and cryptography in a way that still feels unusual today.
Dorothy Crain is known for Ciphers for the Little Folks, a 1916 educational book published by Riverbank Laboratories in Geneva, Illinois. The book was presented as part of "The Dorothy Crain Series" and was designed to spark children's interest in reading, writing, and number work through cipher exercises.
The work is especially distinctive because it introduces young readers to ideas connected with Francis Bacon's biliteral cipher. Library and catalog records also credit Helen Louise Ricketts with the appendix, suggesting the book was part of a broader educational effort rather than a stand-alone commercial title.
Very little confirmed biographical information about Crain herself is easy to verify from major public reference sources. What remains clear is that her name endures through this unusual book, which sits at the crossroads of children's education, puzzle-solving, and the early popular history of cryptography.
