Died. Glenda Farrell, 66, actress; of lung cancer; in Manhattan. Often cast as a tough babe with hair and heart of gold, Farrell began her screen career as a gangster's moll in the 1930 film classic Little Caesar. She went on to wisecrack her way through scores of Hollywood movies, including I Am a Fugitive from a Chain Gang (1932), Gold Diggers of 1937 and the Torchy Blane series. Weary of being typecast, she made a deft transition in the 1950s to motherly roles on television and Broadway.

Died. Helene Weigel, 70, Vienna-born actress-director and flinty widow of Playwright Bertolt Brecht; in East Berlin. Already an accomplished performer when she married Brecht in 1929, Weigel later starred in his drama Mother Courage on the Berlin stage. Anti-Nazi and proCommunist, the couple fled Hitler's Germany in 1933, lived in Denmark and the U.S., then returned to East Germany after the war. For the past 15 years Weigel directed the famed Berliner Ensemble, the repertory company founded by Brecht. "What Brecht prescribed," wrote Critic Kenneth Tynan in 1961, "his widow embodies: the maxim that there is no such thing as a character ungoverned by a social context."

Died. Dr. Donald Dexter Van Slyke. 88, clinical chemist; of cancer; in Garden City. N.Y. A major contributor to the study of amino-acid chemistry and kidney function. Van Slyke applied innovative analytical methods to both clinical and investigative medicine. He was known primarily for his work leading to the detection of acidosis (a condition often leading to diabetic coma) and his studies of kidney disease.

Died. Ejnar Mikkelsen, 90, Danish explorer and author; in Copenhagen. Mikkelsen first indulged his zeal for polar exploration at the age of 16 by walking 320 miles from Stockholm to Goeteborg in an unsuccessful attempt to join an Arctic balloon flight. Later he captured world attention by leading the 1906 Anglo-American polar expedition, a two-year journey that established the fact that there is no land directly north of Alaska. Between 1909 and 1912, Mikkelsen led a mission in search of the diaries of another brave Dane, Mylius-Erichsen, who had died while exploring the northeast corner of Greenland. After recovering some of the ill-fated explorer's papers, Mikkelsen and a single companion were marooned for two years.
