Paul Rubenstein, a founding partner of the accounting firm Holtz Rubenstein, died of natural causes at his Bay Shore home Tuesday. He was 87.

A dedicated accountant and role model in the financial world, Rubenstein gave back to his community by serving on the board of directors for the Long Island chapter of the American Cancer Society and as vice president of the Long Island Philharmonic.

Rubenstein grew up in the Bronx with his parents Norman and Bluma and three siblings. After graduating from high school, he joined the Navy, where he worked as an electrical engineer handling ship communications. One year, he rigged the ship's radio so the captain and crew could listen to the World Series, said his son Chett, of Westport, Connecticut.
