From 1730, Newbery was working as a journeyman for the printer William Carnan in Reading. Upon Carnan’s death, Newbery took over the running of the Reading Mercury and married Carnan’s widow, Mary. The family moved to London in 1744. Newbery became an important early publisher of works for children. He was an innovative and intelligent businessman, issuing the first children’s periodical and the first children’s encyclopaedia, advertising widely, offering discounts to teachers buying in bulk, and publishing other bestsellers, from the annual Ladies Complete Pocket-Book to works by Samuel Richardson and Oliver Goldsmith. From 1751, Newbery also published the works of poet Christopher Smart, a bond strengthened when his stepdaughter Anna Maria Carnan married Smart in 1752. He died a wealthy man in 1767 and was succeeded in business by his son, Francis Newbery. In recognition of Newbery’s contribution to children’s literature, the Newbery medal, introduced in 1922 in the United States, is awarded every year to an outstanding book for children.
