Kenkichi Iwasawa, 81, Henry Burchard Fine Professor of Mathematics, Emeritus, died in Tokyo on October 26.
    A leading researcher in algebra and number theory, Iwasawa was recognized particularly for his work on the theory of algebraic number fields, which became known as "Iwasawa Theory." This earned him several prizes, including the American Mathematical Society's 1962 Cole Prize.
    Born in Japan, Iwasawa graduated from the University of Tokyo in 1940, where he earned his DrSci degree in 1945 and was appointed an assistant professor in 1949. He was a member of the Institute for Advanced Study from 1950 to 1952, when he was appointed assistant professor at Massachusetts Institute of Technology; he was promoted to professor five years later. He was Fine Professor at Princeton from 1967 to 1986.
    Iwasawa was a member of the American Mathematical Society and Mathematical Society of Japan, and a fellow of the American Academy of Arts and Sciences.
    He is survived by his wife Aiko; son Takashi; and two daughters, Kazuko Ihara and Mariko Morodowitch.

Lawrence T. Ellis, 70, former head coach of men's track and field and cross country, died on November 4.
    A 1951 graduate of New York University, where he was a middle distance runner, Ellis came to Prince-ton in 1970, the first African American head coach in the Ivy League. When he retired in 1992, he had coached men's track and field and cross country to a string of championships, including eight of nine Heptagonal Cross Country Championships between 1975 and 1983, four Heptagonal indoor track titles, and seven outdoor titles between 1981 and 1990. He received Coach of the Year honors for 1981-82.
    Ellis also guided the 1984 Olympic team that included Carl Lewis, who won four gold medals at the games in Los Angeles, and he coached U.S. men's teams at four other international meets, including the team that beat the Soviet Union in a dual meet in 1978. After his retirement from Princeton, Ellis served as president of U.S.A. Track and Field from 1992 to 1996, as well as remaining active in Princeton athletics. His death came less than a week after he had accompanied the men's cross country team to New York City, where they won their second consecutive Heptagonal Cross Country Championship.
    Ellis is survived by his wife Shirley; three daughters, Lesley Smalls, Robin Williams and Joanne Glenn; and son Lawrence.
