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
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.
