MUNICH, Germany (AP) _ Adolf Butenandt, whose pioneering work on hormones earned him the Nobel Prize and helped lead to the development of the birth control pill, died Wednesday after a long illness. He was 91.

In 1929, Butenandt isolated the female hormone estrone, and two years later the male hormone androsterone. He isolated the pregnancy hormone progesterone in 1935, when he also synthesized the male hormone testosterone.

He also worked to explain the importance of genes and was the first to isolate hormones in insects.

Butenandt shared the 1939 Nobel Prize in chemistry with Leopold Ruzicka, a Czech. Because of the Nazi dictatorship, he was unable to receive his Nobel until after World War II.

He headed the Max Planck Society for the Promotion of Science from 1960 to 1972, and remained honorary chairman until his death.

Ray Johnson

NEW YORK (AP) _ Ray Johnson, who pioneered collages using images from popular culture, died Friday after jumping or falling from a bridge. He was 67. The death is under police investigation.

By the mid-1950s, Johnson had started assembling collages based on pop figures like Elvis Presley and James Dean. His art combined painting, lettering and found objects as well as abstract mosaic elements.

Johnson also became known for creating whimsical works known as ``mail art'' out of scraps of correspondence.

His works are in the permanent collections of the Philadelphia Museum of Art, the Corcoran Gallery of Art in Washington, D.C., and the Walker Art Center in Minneapolis.

Lord Kagan

LONDON (AP) _ Lord Kagan, who made millions from the invention of a lightweight raincoat and bounced back from the disgrace of a prison term, died Tuesday. He was 79 and had recently suffered a heart attack.

Born in Lithuania, Kagan came to England to study at a college in Leeds in 1937. There he developed a technique for bonding waterproof nylon to wool. In the late 1950s, he patented his nylon-wool invention as Gannex.

As a mark of his close relationship with Prime Minister Harold Wilson, Kagan was knighted in 1970 and made a life peer in 1976.

In 1980, Kagan was convicted of false accounting, involving the export of denim and the theft of indigo dye. He served 202 days in prison and was stripped of his knighthood. He retained the peerage, which can only be invalidated by legislation.

After serving his sentence, Kagan resumed an active role in the House of Lords.

Ron Luciano

ENDICOTT, N.Y. (AP) _ Ron Luciano, an American League umpire for 11 years noted for his flair and showmanship, was found dead Wednesday in the garage of his home. He was 57.

An autopsy was ordered, but a preliminary investigation showed no signs of foul play.

In a profession that traditionally demanded an unobtrusive presence, Luciano practiced his craft with flair and animation. He was a big, lumbering man who waddled across the field and gesticulated strongly on the bases.

Luciano worked the 1974 World Series and the AL championships in 1971, 1975 and 1978. The 300-pound former football lineman retired from baseball in 1980, then worked as a television commentator for NBC and wrote a book about his baseball experiences, ``The Umpire Strikes Back,'' in 1982.

Georgeanna Mitchell Stanton

HOUSTON (AP) _ Georgeanna Mitchell Stanton, former newspaper reporter and wife of University of Houston journalism professor Ted Stanton, died Sunday of cancer. She was 65.

Stanton worked as wire editor for newspapers in Oklahoma before joining the Corpus Christi Caller-Times in 1951. She covered education there until 1956. From 1962 to 1969, she was Staten Island correspondent for the Newark (N.J.) Evening News.

Stanton wrote for a local magazine in Houston in 1984. Her husband, Ted Stanton, is associate director for undergraduate studies in the University of Houston School of Communication.

She is survived by her husband; daughters, Robin and Katie; sons, Kevin and Michael; and a sister, Frances.

CAMDEN, Maine (AP) _ Kay Aldridge Tucker, a philanthropist, actress and model who was one of the most photographed women in the country during the 1930s, died Jan. 12. She was 77.

She was screen-tested for the role of Scarlett O'Hara in ``Gone With the Wind'' and appeared in the 1942 musical ``DuBarry Was a Lady.'' She retired from acting in 1945.
