Arlene Stringer-Cuevas, a former city councilwoman in the 1970s and mother of Comptroller Scott Stringer, passed away Friday morning from complications of the coronavirus.

She was 86 years old.

The comptroller announced his mother’s death on Twitter Friday, saying it’s a “heartbreaking moment for me, my wife, and our entire family.”

Stringer called the Bronx-born ex-public school teacher and lifelong New Yorker a “genuine trail blazer” — proudly recalling how she was the first woman elected to represent Washington Heights on the council, a post she held from 1976 to 1977.

In 1978, she took a job at the city’s Human Resources Administration heading the agency’s program contract analyst unit, which she held until retiring in 1994.

She is also survived by her husband, Carlos Cuevas, a former Bronx deputy borough president and city clerk, and a son, David.

“The loss I feel today is incalculable,” Stringer said. “My mother showed me at an early age the importance and the great challenge of public service.

“She also helped me become the person I am today. If there is any silver lining, it’s that her memory — and the example she set for so many people — will be a legacy that will live on.”

Mayor Bill de Blasio paid tribute to Stringer-Cuevas, telling reporters on Friday that she was “trailblazer in public life in the city” for all women.

“Our condolences [from] all of us here in City Hall… to Scott and his whole family,” Hizzoner said.

“It’s a reminder of how personal this crisis is.”
