Milestones: Apr. 5, 1968

Married. Joan Baez, 27, premier folk singer; and David Harris, 22, a peace lecturer; (see RELIGION).

Married. Arthur Kopit, 30, playwright with a knack for titles (Oh Dad, Poor Dad, Mamma's Hung You in the Closet and I'm Feelin' So Sad, The Day the Whores Came Out to Play Tennis); and Leslie Ann Garis, 24, Vassar graduate and granddaughter of the late Howard Garis, creator of the Uncle Wiggily stories; in Riverside, Conn.

Married. George Plimpton, dervish of the Manhattan whirl, sometime author and would-be athlete, who pitched against baseball's All-Stars, quarterbacked the Detroit Lions and boxed against Archie Moore, but couldn't get himself to the altar until he was 41; and Freddy Espy, 26, Manhattan photo-studio assistant, a petite, slightly bewildered blonde whom he met at a party in 1963; in Manhattan. Considering the wait, George was in a positive sprint. Poor Freddy didn't find out until 10:30 a.m., seven hours before her wedding. Peter Duchin's wife, Cheray, who fixed up a friend's apartment for the ceremony, was luckier—George told her at 9 a.m. His father and mother got there in time, but his brother couldn't. Still, Jackie Kennedy was on hand with Caroline; so were Poet Marianne Moore, Novelists Philip Roth, William Styron, Terry Southern and about 30 other chums. Then everybody raced off to a little Second Avenue bistro for supper. Honeymoon? Later, baby. George headed for Indiana to campaign for Bobby.

Died. Colonel Yuri A. Gagarin, 34, Soviet cosmonaut, who on April 12, 1964 became the first man in space with a one-orbit flight aboard Vostok I; in the crash of an unannounced type of plane, also killing Colonel Vladimir S. Seryogin, 46; near Moscow. Short (5 ft. 3 in.) and stocky, the son of a rural carpenter, Gagarin won his pilot's wings in 1957, the year of the Sputnik, shortly after was tapped for the first class of cosmonauts. His historic 89-minute orbit of the globe made him Russia's greatest hero since World War II.

Died. Paul J. Hallinan, 56, Roman Catholic Archbishop of Atlanta, one of the South's foremost advocates of social and religious liberalism; of acute hepatitis; in Atlanta. Hallinan's first act after his appointment in 1962 was to order desegregation of schools and other Catholic institutions under his jurisdiction; in 1965, he sent priests and nuns to the Selma, Ala., civil rights march, and earlier this month he bluntly advised Atlanta's citizens to open their neighborhoods "so Negroes can exercise the right of every American to live where he wishes."

Died. Nicholas Samstag, 64, author and former (1943-60) promotion director of TIME; of cancer; in Manhattan. A recognized, often flamboyant practitioner of his trade, Samstag wrote a number of successful books, including Bamboozled and The Uses of Ineptitude and, while running his own agency after 1960, took ads in Manhattan newspapers offering to teach anyone everything he knew about the advertising and promotion business—for a fee of $10,000. The day after Samstag's death, his fifth wife, Suzanne, 38, was found dead in her room at a Kennedy Airport hotel.
