Thomas Boreman was one of the earliest English children's book publishers.
His Three Hundred Animals was published ca 1730. Boreman's earliest works included his 1740 Gigantick Histories, miniature books with illustrations and a list of subscribing readers, including the names of children as well as parents. He followed this two-volume publication with Curiosities in the Tower of London, with illustrations of animals in the Tower Zoo.
He published approximately a dozen titles. In 1742, he produced a book purporting to be the biography of Daniel Cajanus, The History of Cajanus, the Swedish Giant, from his Birth to the Present Time.
From the preface to Gigantic History:
"During the Infant-Age, ever busy and always inquiring, there is no fixing the attention of the mind, but by amusing it."
