Mafalda DiMango, a longtime Dyker Heights resident and one of the longest-serving school board members in the city’s history, died on Aug. 2. She was 91 years old. DiMango was a staunch community and education activist, spending more than 40 years advocating for students in School District 20 — which includes Bay Ridge, Fort Hamilton, Borough Park, and part of Bensonhurst — as a member of the school board and the Community Education Council.

She also spent many years as a member of the Dyker Heights Civic Association and Community Board 11, and received many awards over the years for her service, including the Civic Award, the Woman of the Year Award, and the Hidden Treasure of the Community Award, all from the Bay Ridge Community Council.
