Former University of Chicago President Robert Zimmer is stepping down as chancellor of the school as he continues to fight glioblastoma, an aggressive form of brain cancer.
He will remain chancellor emeritus. He retired as president at the end of last August.
"As Bob assumes this new position, the Board of Trustees wants to express our extraordinary admiration for Bob’s long-time service to the university, including 15 years as president," said Board of Trustees Chairman David M. Rubenstein in a statement.
"I know I speak for the entire university community in saying that Bob remains in our thoughts, and we hope he and Shadi (Bartsch, his wife) will continue to address his health challenges to the extent that he and his medical team can best do so."
A mathematician, Zimmer's presidency was one of the most important of the university's. He was a remarkable fundraiser, his chief job as chancellor, who saw the school expand its footprint in Hyde Park and surrounding neighborhoods and maintained its flinty reputation for academic excellence among other elite post-secondary institutions.
