Sharon C. "Sherry" Lietman, a former Bryn Mawr School mathematics teacher who worked to instill in her students a love of numbers and puzzles, died of cancer May 1 at Blakehurst Retirement Community in Towson. She was 81.
"Sherry influenced scores of Bryn Mawr Lower School girls when it came to math," said Peggy Bessent, former director of the lower school who later became associate head mistress.
"She had a passion for problem solving and math puzzles. She was very patient with her students and wanted them to achieve success. She was a very intuitive and influential teacher," said Ms. Bessent, who retired from Bryn Mawr in 2013.
