Joseph Cundall (22 September 1818 – 10 January 1895) was a Victorian English writer under the pseudonym of "Stephen Percy", a pioneer photographer and London publisher of children's books.
He trained as a printer in Ipswich, and aged 16 found work in London with Charles Tilt, a bookseller and publisher.
In 1843 Cundall became publisher of the Home Treasury children's books, a series conceived and edited by Henry Cole under the pseudonym Felix Summerly.
In 1848, he transformed the antagonist in "The Story of the Three Bears" from an ugly old woman to a pretty little girl in his Treasury of Pleasure Books for Young Children.
Cundall is noted for his photographs detailing the construction of the SS Great Eastern between 1854 and 1856, and his portraits of Crimean Heroes in 1856.
