City officials and friends, family, and colleagues of the late Sonia Weitz were among those who gathered at Brooksby Farm recently to dedicate a bench with a memorial plaque in her honor. The June 24 event was held the day after the second anniversary of the death of Weitz, a Holocaust survivor and longtime Peabody resident who was cofounder and education director of The Holocaust Center, Boston North, housed at the Peabody Institute Library. “As a poet, author, and spokeswoman for her generation, she put a face on Holocaust history,” Harriet Wacks, the center’s executive director, said of Weitz in a statement. “A remarkable woman who became a role model for the generations after, she was beloved by everyone who had the privilege of hearing her share her experiences during the Holocaust. Her mission was to encourage others to apply the lessons of the past to the present.” Wacks, Mayor Ted Bettencourt, and Weitz’s daughter, Sandy, were among those on hand for the dedication. Others included Rena Finder, a lifelong friend of Weitz and Holocaust survivor; and Joanne Patton, daughter-in law of the late US World War II General George S. Patton Jr., and a friend of Weitz. In May, a newly planted tree and a memorial plaque were dedicated in Weitz’s memory outside the Peabody Institute Library.
