Frederick Sillman ’58

Fred died Jan. 14, 2026. He was 89

Born in 1936, Fred grew up in New York City and attended Deerfield Academy, Princeton, and then Harvard Medical School. He loved them all, yet he remained humble and informal throughout his life. He appreciated what each school offered and built lasting friendships along the way.

Fred was a gynecological oncologist and worked at SUNY Downstate in Brooklyn, N.Y., and later at Mass General Brigham in Boston. He treated numerous patients while mentoring fellows, residents, and medical students. His contributions to the field of women’s health included research on cervical cancer, HPV, and pre-cancerous lesions.

Fred was a warm and kind person who had a great sense of humor. Beyond work, he had many interests. He loved sports of all kinds, especially cycling in multi-colored spandex outfits. He marched to the beat of his own drum, was a relentless optimist, and loved adventures.

Fred is survived by his wife, Jane; his children, Kathryn and her husband Ray, and Eric and his wife Rebecca; grandchildren, Sophie, Theo, Jules, Toby, and Lena; and sister, Anne.
