Changes of the Week

P: James D. Mooney, 70, former General Motors executive and onetime president and board chairman of Willys-Overland Motors, Inc., was elected president of Hoe & Co., biggest U.S. manufacturers of rotary printing presses. He succeeds Arthur Dressel, who resigned because of illness. Mooney lands in the thick of two fights: 1) a campaign by a stockholder faction to reinstate Dressel's ousted predecessor, Joseph L. Auer; and 2) an A.F.L. machinists' strike that has closed Hoe's main plants since January.

P: Seymour Mintz, 42, Admiral Corp.'s vice president in charge of advertising, was appointed president of CBS-Columbia, CBS's chief manufacturing division (radios, TV sets, phonographs).

P: Malcolm S. Mackay, 45, vice president of Northwest Airlines, Inc., was named executive vice president, a title befitting his current duties. Nominally in charge of the continental division, Mackay has been Northwest's acting boss since January, when hard-driving President Harold R. Harris was laid low by a heart ailment.

P: Noah Dietrich, 65, No. 2 man in the Howard Hughes empire and a key figure in the blow-off of Hughes Aircraft (TIME, Oct. 5), announced that he intends to retire "as soon as I can clean up the necessary details," probably within the next six months. Explained Dietrich, who went to work for Hughes in 1924 as his personal assistant: "I'm tired. Between the troubles at RKO and Hughes Aircraft and the troubles in my own domestic life [he is seeking a divorce], I've had it. All I want to do is go out and hunt and fish."
