Does being the widow of a black icon exempt one from aging? Coretta Scott King and Betty Shabazz are both extraordinarily well preserved for women who must be, to be charitable, in their 60s, but neither of them can compete with the downright Dorian Grayish Rachel Robinson, wife of Jackie, who is in town promoting her gorgeous book, Jackie Robinson: An Intimate Portrait, a coffee-table volume containing more than 300 photos chronicling her husband’s decline from dynamic youth to distinguished middle age to frail final days—while Rachel gazes serenely on, perhaps somehow aware that the ravages of mortality will pass her by. The author pic on the book’s dust jacket doesn’t look all that different from the photo of Rachel taken on her first date with Jackie in 1941. See if the camera lies, when Mrs. Robinson appears at 4 p.m. at Borders, 534 N. Frederick Ave., Gaithersburg. FREE. (301) 921-0990. Also appearing on Monday at 8 p.m. at the National Museum of American History’s Carmichael Auditorium, 14th & Constitution Ave. NW. $15. For reservations call (202) 357-3030. (James Lochart)
