Former Brookhaven Town councilwoman and environmental activist Regina “Reggie” Seltzer “died overlooking the gardens she ardently tended and the Great South Bay, two of her favorite places,” read a death notice in the New York Times July 1.

She died at her Bellport home June 29 at the age of 86.

Seltzer is survived by her son Eric, his wife Nealle and three granddaughters: Veronica, Jean and Bryn.

Reggie Seltzer left behind a legacy of good works.

In 1979, Seltzer was named Woman of the Year in Environment by this newspaper.

At that time, she was recognized by Cathy McKeen, who wrote: “Since she won a seat on Brookhaven’s Town Board four years ago Regina Seltzer has been an advocate of protecting the environment.”

McKeen went on to list her many accomplishments, among them the creation of the town’s Department of Environmental Protection, advocating zoning reform to address haphazard planning and growth and a new sanitary code.

Seltzer was born to Jewish parents in Poland in 1929. Three years later, seeing the injustice and brutality inflicted upon Jews in their town — and fearing what would follow — her parents left Poland, bound for Palestine. In 1937, they followed family and immigrated to New York.

As an adult, Seltzer first worked as a school teacher and librarian, according to Brookhaven Town Supervisor Edward Romaine (R), who eulogized her at the start of the June 30 town board meeting.

She was a councilwoman and member of the town’s planning board. She had returned to school to earn a law degree in her 50s and worked on many environmental issues, often pro bono. She was a true civic leader, Romaine said.

“[Reggie] made a huge difference in the Town of Brookhaven,” said Romaine. “She was brighter than light, easy to work with, principled, honest, straightforward — someone that we’ll all miss in this town government. … I’ve ordered flags at Town Hall to fly at half mast in her honor.”

Friends and colleagues also expressed their grief at the board meeting. Sherry Binnington, of Bellport, met Seltzer in the 1960s, when they became neighbors.

“Reggie Seltzer was a genuine person who had a conscience and was concerned about other people,” Binnington said during the public participation part of the meeting. “She believed that you should try to do everything you can when you see things that are not right.”

Another activist and friend, MaryAnn Johnston, had this to say, “When I first started working as an activist, Reggie was a source of constant encouragement and inspiration.

“She taught me how to do this work … with an uplifted heart. And to celebrate the victories — that they’d be few and far between, but that when you did the job well, they would matter and they would last. It would be what you left behind.”
