Mary Cooper (publisher) [SEP] Introduction
Mary Cooper (d. August 5, 1761) was an English publisher and bookseller based in London who flourished between 1743 and 1761. With Thomas Boreman, she is the earliest publisher of children's books in English, predating John Newbery. Cooper's business was on Paternoster Row. She was the widow of printer and publisher Thomas Cooper, whose business she continued. Thomas Cooper had published a reading guide in 1742, "The Child's New Play-thing", and his wife published an edition of it after his death. Active from 1743 to 1761, she is notable especially for publishing "Tommy Thumb's Pretty Song Book" (1744), "the first known collection of English nursery rhymes in print".
