Samuel Richardson was an English writer and printer known for three epistolary novels: Pamela; or, Virtue Rewarded (1740), Clarissa: Or the History of a Young Lady (1748) and The History of Sir Charles Grandison (1753). He printed almost 500 works, including journals and magazines, working periodically with the London bookseller Andrew Millar. Richardson had been apprenticed to a printer, whose daughter he eventually married. He lost her along with their six children, but remarried and had six more children, of whom four daughters reached adulthood, leaving no male heirs to continue the print shop. As it ran down, he wrote his first novel at the age of 51 and joined the admired writers of his day. Leading acquaintances included Samuel Johnson and Sarah Fielding, the physician and Behmenist George Cheyne, and the theologian and writer William Law, whose books he printed. At Law's request, Richardson printed some poems by John Byrom. In literature, he rivalled Henry Fielding; the two responded to each other's literary styles.
