Died. Werner Heisenberg, 74, iconoclastic German nuclear physicist who joined with Albert Einstein, Max Planck and others in repealing some of Newton's laws of physics during the 1920s and 1930s; in Munich. Heisenberg's outstanding contribution, for which he won the Nobel Prize at 31, was the formulation of the uncertainty, or indeterminacy principle. It states that there is an ultimate limit on physical measurement or observation in scientific experiments because the very act of measurement changes the behavior of objects under scrutiny. Unlike many of his scientist friends, Heisenberg remained in Germany under the Nazi regime and carried out atomic research.

Died. Milton Harry Biow, 83, advertising man and popularizer of such classic catch phrases as "Call for Philip Morris" and "Bulova Watch Time" and creator of radio's celebrated The $64 Question; in Manhattan.

Died. Hilmar Robert Baukhage, 87, newsman and radio commentator who announced the start of World War II in a historic on-the-scene broadcast from Berlin in 1939, then on Dec. 7, 1941, aired the first live newscast from the White House with a marathon eight-hour report on the Pearl Harbor attack; in Washington, D.C. With "Baukhage talking" as his sign-on, the broadcaster was an NBC and ABC mainstay for two decades.

Died. Hans Richter, 87, painter, film maker and one of the originators of the Dada movement in art; in Locarno, Switzerland. While many of Richter's revolutionary friends, such as Painters Max Ernst and Marcel Du-champ and Sculptor Hans Arp settled into more traditional art forms, Richter gave up his easel for Dadaist and Surrealist film making. He made his first film, Rhythm 21, in 1921 and his best, Dreams That Money Can Buy, in 1947. In 1941 Richter fled Nazi Germany and came to New York, where he taught cinema for many years. In 1965 he published his authoritative account, Dada: Art and Anti-Art.

Died. Pathologist George Hoyt Whipple, 97, co-winner of the Nobel Prize for Medicine in 1934 for research demonstrating that a liver diet could control pernicious anemia; in Rochester. A Yale graduate, class of 1900, he received his medical degree in 1905 from Johns Hopkins, where he remained until 1914 studying and teaching pathology. After six years at the University of California, Whipple in 1921 became a founding father and first dean of the new University of Rochester medical school, which he headed for 32 years.
