 Relations between Rombauer and Bobbs-Merrill, never cordial, worsened during the late 1940s, and in the fracas Marion Becker gradually assumed increasing responsibility, at first regarding the book's design, and eventually its content.Partly for legal reasons, the 1951 edition was published with Marion Rombauer Becker listed as co-author, and she received 40% of the royalties.The authors strongly resisted the publisher's wish to illustrate the book with photographs and instead embellished the book with simple, functional line drawings by Ginnie Hofmann, a friend of Becker's.Becker was a passionate advocate of healthy eating, and the 1951 edition was marked by an increased emphasis of such topics as whole grains and fresh produce.
