Interview with Hyman Bass

TL;DR

This interview chronicles Hyman Bass's seven-decade mathematical life, spanning foundational work in algebra, homological methods, and algebraic K-theory, followed by a major shift toward mathematics education. It traces his development from Princeton and Chicago, through the Congruence Subgroup Theorem and Bass–Serre theory, and includes his Bourbaki involvement and later education-reform leadership. The discussion foregrounds how Bass integrates deep theoretical insights with a commitment to education, including the TeachingWorks initiative and the concept of connection-oriented mathematical thinking. Together, the narratives illustrate a career where abstract structure and practical pedagogy mutually inform and enrich one another.
