Born. To Joan Baez, 28, queen of American folk music, and David Harris, 23, who started serving a three-year sentence in federal prison last July for refusing induction into the Army: their first child, a son; in Palo Alto, Calif.
Divorced. Groucho Marx, 74, most durable of slapstick's famed brothers; by Edna Marx, 38, his third wife; on grounds of mental cruelty; after 15 years of marriage, in Santa Monica, Calif. Settlement: $21,000 alimony, $337,000 from Groucho's TV residuals and 50% of the proceeds from the sale of their $350,000 home.
Died. Stephen Potter, 69, the greatest contemporary gamesman of them all (see MODERN LIVING).
Died. Vicki Cummings, 50, stage and television comedienne, noted for her sardonic wit; of cancer; in Manhattan. On and off the stage, she had a voice as brassy as Ethel Merman's and a tongue as agile as Dorothy Parker's; she made her Broadway debut in 1931's Here Goes the Bride, scored hits in 1943's Voice of the Turtle, 1953's Mid Summer and 1966's The Butter and Egg Man revival, and appeared in more than 200 TV shows, most notably The Man Who Came to Dinner and Burlesque.
Died. Claude Dornier, 85, German aeronautical engineer whose career kept him in the front rank of his country's aircraft industry for five decades; in Zug, Switzerland. Dornier designed the world's first metal airplane in 1911, built thousands of bombers and fighters in both world wars, and in recent years experimented with a series of novel vertical takeoff and landing craft. But his greatest fame still stems from the mammoth DO-X flying boat built in 1929. It had twelve engines, a wingspan of 157 ft. and a passenger capacity of 169. Uneconomic though it was, the DO-X could fly the Atlantic and was the ancestor of today's even bigger jumbo jets.
Died. Marshal Kliment Voroshilov, 88, one of Soviet Communism's ranking figures for half a century; in Moscow. Voroshilov was a tireless agitator during the 1917 Bolshevik revolution, rallying workers and soldiers, helping to organize the dreaded Cheka (secret police); during the civil war that followed, he distinguished himself as one of the founders of the Red armed forces, and in 1925 was appointed Commissar of War. Blindly loyal to Stalin, in 1935 he was named a Marshal of the Soviet Union, and rose to the post of assistant chairman of the party's defense committee. With Stalin's death in 1953, he became President of the U.S.S.R., a post from which he was dismissed seven years later, after opposing Khrushchev's 1957 bid for power.
