Maria Esther Zuno

First Lady

Maria Esther Zuno, 74, wife of former Mexican President Luis Echeverria and a leader known for championing women's rights and domestic social and cultural programs, died of diabetes Dec. 4 in Mexico City.

Among her priorities as first lady were support of domestic social programs and equal rights for women.

She also promoted Mexican cultural traditions, conducting goodwill tours in other countries to share traditional dance, dress, music and art.

Ms. Zuno was married for 54 years to Echeverria, who governed Mexico from 1970 to 1976. They met at the home of Mexican muralist Diego Rivera, married in 1945 and had eight children.

Sam Treiman

Particle Physicist

Sam Treiman, 74, who in 1958 with a colleague, Marvin Goldberger, deduced a relationship between the strong and weak forces of elementary particle physics, died of leukemia Nov. 30 at a hospital in New York.

The Goldberger-Treiman Relation helped explain that some deep symmetries govern the interactions of elementary particles. It helped lead to the theory of spontaneous symmetry-breaking that underlies the much grander theory of particle physics called the Standard Model.

Dr. Treiman was noted for his teaching skills. Among his students was Dr. Steven Weinberg, who won the Nobel Prize in Physics in 1979 for his work in unifying the weak and electromagnetic forces.

Masaru Sato

Music Arranger

Masaru Sato, 71, the music director for filmmaker Akira Kurosawa, died Dec. 5 at a hospital in Tokyo after falling ill at a party in his honor. The cause of death has not yet been determined.

Mr. Sato, who wrote the music for such Kurosawa films as "Red Beard," "Sanjuro," and "Yojinbo," with its samurai battles, began his career in 1952 after graduating from music school in Tokyo. He wrote the music for "Godzilla Raids Again" in 1955 and began working with Kurosawa in 1957.

He wrote the scores for some 308 films, the last of which, "After the Rain," was based on a script by Kurosawa, who died in 1998 at the age of 88.

Richard M. Eakin

Zoology Professor

Richard Marshall Eakin, 89, a retired University of California at Berkeley zoology professor who captivated generations of students with costumed impersonations of scientific pioneers, died Nov. 25 at his home in Danville, Calif. The cause of death was not reported.

Dr. Eakin, who retired in 1977, enlivened the otherwise dry subjects in his zoology course with depictions of historical figures. He spent hours putting on a flowing white beard and makeup to look like Charles Darwin for a lecture on evolution. He dressed as 19th-century monk Gregor Mendel to discuss heredity.

Clark A. Wyly

Clergyman

The Rev. Clark A. Wyly, 88, the pastor of Great Neck Baptist Church in Virginia Beach in the 1980s, died of respiratory failure Dec. 3 at Inova Mount Vernon Hospital. He lived in Woodbridge since 1996.

He was born in Fort Worth and joined the Navy in 1927. He served in the Navy and Merchant Marine during World War II, then graduated from California Baptist Seminary and worked primarily in Colorado and California.
