Stanley S. Treitman died of natural causes at the age of 98 on February 18, 2025 at NewBridge on the Charles Senior Living in Dedham. He is survived by his loving wife and life partner of 76 years, Ruth, and his four children, Rick, Bob, Beth, and Jim.
Born in Los Angeles to Sigmund and Celia Treitman, Stan attended LA public schools and served in the Navy as a radio technician in the Philippines during the closing period of World War II. Upon his return, he enrolled at UCLA where he met Ruth. After UCLA he did graduate work at Cal Berkeley, before returning to Southern California to teach high school science in Colton.
Stan was an early member of the Physical Sciences Study Committee (PSSC) and helped develop a new method of hands-on science physics education. Before he implemented PSSC at Colton High, a handful of students studied physics – within a few years, five full sections of students enthusiastically enrolled in his classes. In 1965 Stan joined a USAID/Harvard project to implement PSSC at a model secondary school in Nigeria, where the family lived for two years.
Upon returning to The States, Stan taught in the science department at Wheelock College. The family moved to Wellesley where Stan and Ruth lived for over 50 years. In 1982, Stan and Ruth, who taught math at Dana Hall, left the world of education and went into business, opening a retail software store in Burlington. Stan, Ruth, Jim, and later Rick and Bob, built Softpro into a successful software and technical bookstore.
Upon retirement in 2005, Stan continued to share his technical and accounting expertise in his numerous volunteer positions. He served Wellesley Weston Lifelong Learning and the Friendly Aid Society. He was a board member and VP/Membership Chair of The Jewish Genealogical Society of Greater Boston who honored him in 2018 for his outstanding contributions building their database and communications technology. Ruth and Stan were among the founders of Wellesley Neighbors where they published the newsletter, built the web site, and took part in many of the activities – particularly the jazz concerts.
Ruth and Stan spent summers on Newfound Lake in New Hampshire for many years where the family gathered and many of their grandchildren learned to swim. The lake house continues to host memories for those Stan leaves behind.
In 2018, they moved from Wellesley to NewBridge on the Charles, where they joined old friends and made new ones. They were regulars at the evening concerts and lectures for many years. For many NBOC computer users, Stan was the help desk, and he used his expertise at page layout for newsletters for multiple organizations including NBOC publications.
In addition to the love of his life, Ruth, Stan leaves behind his children Rick (Louise) of Lexington, Bob (Leslie Fisher) of Concord, Beth (Michael) Paysnick of Longmeadow, and Jim (Chris Garlasco) of Golden, Colorado. He also leaves nine grandchildren, Sarah Paysnick, Annie Treitman, David Paysnick, Kate Brown, Amy Paysnick, Jo Hogan, Lauren Treitman, Olivia Treitman, and Rachel Treitman, and nine great grandchildren.
The family thanks his caregivers, Dianne Wilks, Pearl Cashman, and Vida Atakpo, and hospice nurses who worked hard to keep Stan comfortable and at peace in his final days.
A service in his memory will be held at NewBridge on the Charles at 2pm on March 30.
Donations in Stan’s memory can be made to the Wellesley Food Pantry (wellesleyfoodpantry.org/) or the Newbridge Employees’ Scholarship Fund.
