Diane Herrmann, the co-director of Undergraduate Studies in Mathematics and a Senior Lecturer, described Sally as “a force of nature.” Herrmann worked with Sally as a teacher, mentor and then as a colleague for the past 30 years.
“He was passionately interested in mathematical education at all levels,” said Herrmann, who with Sally co-founded the Young Scholars Program, a groundbreaking enrichment program for mathematically talented seventh through 12th graders.
One student who benefitted from the Young Scholars Program starting in seventh grade was Maryanthe Malliaris, who is now an assistant professor in UChicago’s department of mathematics. She recalled the experience as “exhilarating” and “decisive for my future in mathematics.”
“He had an incredible psychological astuteness, and a forceful clarity,” Malliaris wrote in an email. “He devoted a great deal of his time to creating possibilities for others. He concerned himself with the field as a whole. He would be there on Saturdays, on evenings, in the summer. His door was always open… He would show by example what it is to be a great human being.”
David Vogan, AB, SM, ’74, another former student of Sally’s, went on to be a Professor of Mathematics at the Massachusetts Institute of Technology and president of the American Mathematical Society.
“What distinguished Paul Sally was not only his passion for mathematics, but also his love and care for everyone studying mathematics,” Vogan said. “He had an appreciation for all the different levels of mathematics. He was a remarkable individual who seemed to have an unlimited supply of energy.”
