Susan Barrett (Matthews) Peltz of Lexington, known to all as Barrie, died suddenly on February 2, 2021 after an accident that resulted in a catastrophic brain injury. Born in Baltimore, Maryland, daughter of the late Susan and Harry Joseph Matthews, Jr., Barrie attended Garrison Forrest School for Girls before moving north to attend Wheaton College, graduating Phi Beta Kappa in 1969. She worked as a Beth Israel Hospital administrator and met and married Mason “Toby” Peltz in 1973. The couple moved to Lexington and had two daughters, Samantha Peltz Straub and Kate Peltz. Barrie and Toby divorced decades later but remained partners in grandparenting Sam’s children, Allie Straub and TJ Straub, and Kate’s children, Ethan Elms and Caroline Elms, and being in-laws to their daughters’ husbands, Patrick Straub and Frank Elms. Preceded in death by her sister, Louise Longstreth, Barrie was a devoted aunt, to Louise’s children, Susan Maroto and Mark Longstreth, as well as their spouses and children. Methodical, whip-smart and boundless in her energy, Barrie contributed her talents and humor to numerous companies and organizations, but it was her volunteer efforts for, and political involvement in, the town of Lexington that most gratified her. In addition to promoting the campaigns of several elected town leaders, she served as a member of the PTA, chaired the Lexington School Committee in 1996, 1997 and 1998; and was a member of the Lexington Historical Society. Barrie loved her town, stood up for the causes which compelled her, and treasured the many neighbors who became friends during her 44 years as a resident. A gifted fiber artist, Barrie shared her knitting, needlepoint, and fabric projects with all of her loved ones. Perhaps it was having her birthday on the first day of spring that contributed to her green thumb. Keeping busy in her garden, Barrie nurtured her plants and vegetables as friends. Excited for Inauguration Day, Barrie was thrilled to see Kamala Harris become the Vice President of the United States. When she was not reading or wordsmithing (why use a regular word if a fancier one is available?), she listened to National Public Radio.
