Seymour "Sy" Schuster was a relentless advocate for diverse students and faculty at Carleton College in Northfield, where he was an accomplished math professor, mentor and social justice activist.
Schuster was a friend and campaign adviser to the late U.S. Sen. Paul Wellstone, who had been a fellow Carleton professor. He was active in Rice County politics and served on the State Central Committee of the DFL Party.
Schuster, 94, died Oct. 28, just days after contracting COVID-19.
"I couldn't have done what I did at Carlton without having Sy as a warrior for justice," said the Rev. Jewelnel Davis, university chaplain and associate provost at Columbia University in New York, who collaborated with Schuster in the 1980s and 1990s.
"There weren't many African American women working as chaplains in the country," she recalled. "Sy was not only there in terms of supporting my work in justice, but I always knew I could count on him personally."
Schuster was born in the Bronx in New York City in 1926, the son of Oscar and Goldie Schuster. He enlisted in the U.S. Navy Reserve when he was 18, and later pursued academic studies, earning a Ph.D. from Pennsylvania State University.
In 1958, Schuster and his wife, Marilyn, moved to Northfield to begin teaching at Carleton, where he spent most of his career until retiring in 1994. He left Carleton for just five years, starting in 1963, to lead the College Geometry Project, a series of films to help elementary and secondary math teachers improve their instruction. He was an enthusiastic and popular teacher, and over the years also published several books and more than 30 scholarly papers.
Dave Appleyard said he was a freshman majoring in history when he took Schuster's first calculus class in 1958. Inspired, Appleyard switched his major to mathematics with a goal of teaching high school. Schuster urged him to go for a Ph.D., and Appleyard did. Coming full circle, he wound up teaching in Carleton's math department with his mentor, too.
