Alfred A. Knopf, Inc. is a New York publishing house, founded by Alfred A. Knopf, Sr. in 1915. It was acquired by Random House in 1960 and is now part of the Knopf Doubleday Publishing Group at Random House, which has been owned since 1998 by the German private media corporation Bertelsmann. The publishing house is known for its borzoi colophon (shown at right), which was designed by co-founder Blanche Knopf. Many of its hardcover books later appear as Vintage paperbacks. Vintage is a sister imprint under the Knopf Publishing Group. In late 2008 and early 2009, the Knopf Publishing Group merged with the Doubleday Publishing Group to form the Knopf Doubleday Publishing Group.
