Publisher:Putnam

Founded in 1838 as a book retailer in New York City, Wiley & Putnam within ten years began publishing books under the leadership of George Palmer Putnam. When he died in 1872, the company was ran by his three sons, becoming G. P. Putnam's Sons, a name that continues to this day. In 1965, Putnam purchased the paperback publisher Berkley Books. When Putnam purchased Grosset and Dunlap in 1982, it also acquired Ace Books in the deal. In 1996, Putnam itself was acquired by the Penguin Group, but remains a separate publishing company.
