DIED. Fazlur R. Khan, 52, Bangladesh-born structural engineer whose ingenious "bundled tube" design was applied to the construction of Chicago's 1,804-ft., 110-story Sears Tower, the world's tallest building; of a heart attack; in Saudi Arabia. Khan's innovative approach brought together narrow, silo-like structures to form a thicker tower, thus doing away with the conventional skeleton frame.

DIED. Karol ("Ken") Harris, 83, Hollywood cartoonist who helped create such lunatic movie characters as Bugs Bunny, Porky Pig, Daffy Duck, Wile E. Coyote and his nemesis, the Road Runner; in Woodland Hills, Calif. Harris also helped design the animation for the Pink Panther movie series and the film The Phantom Tollbooth.

DIED. Nathan f. Twining, 84, tenacious, cigar-chomping Air Force general who served as Chairman of the Joint Chiefs of Staff from 1957 to 1960; in San Antonio. A World War II commander of U.S. air campaigns in Europe and the South Pacific, Twining was an unfaltering proponent of airpower and military might. B-29s under his command dropped the atom bombs on Hiroshima and Nagasaki.

DIED. Carl Orff, 86, German composer who turned his back on complex modern styles to fashion a highly personal idiom of folklike melodies and elemental rhythms; in Munich. In Carmina Burana, a 1936 cantata based on writings collected by a 13th century Benedictine monk, Orff used simple, vigorous tunes and choral chants to celebrate the joys of food, drink and love. He pared down to an even more stylized primitivism in his Antigonae (1947-48) and Oedipus der Tyrann (1959).

DIED. Harriet Stratemeyer Adams, 89, children's book author of many of the gee-whiz adventures in series like Nancy Drew, the Hardy Boys, Tom Swift and the Bobbsey Twins; in Pottersville, N.J. Writing under such names as Carolyn Keene, Franklin W Dixon, Victor W. Appleton and Laura Lee Hope, Adams spun out more than 200 tales during a 52-year career. Adams was one of several writers who worked for the juvenile series' controlling corporation, the Stratemeyer Syndicate, founded by her father Edward more than 70 years ago.

DIED. Helene Deutsch, 97, eminent psychoanalyst and authority on myths and the psychology of women; in Cambridge, Mass. The Polish-born Deutsch, who was the first female psychoanalyst to be analyzed by Sigmund Freud, directed the Vienna Training Institute before immigrating to the U.S. in 1934. Rebellious in her youth and politically active all her life, Deutsch insisted that Freudian theory could liberate women. But many feminists have attacked her work, describing it as support for Freud's misogynous theories.
