Random House is the largest general-interest trade book publisher in the world. The publishing house was founded in 1927 by Americans Bennet Cerf and Donald Klopfer, who had acquired the Modern Library imprint from publisher Horace Liveright two years before. As for the name, Cerf said, "We just said we were going to publish a few books on the side at random," and Random House was born. The company entered reference publishing in 1947 with the American College Dictionary. Random House acquired Alfred A. Knopf, Inc in 1960 and Pantheon Books in 1961.
