Natacha Pehlman Dykman, a former president of the League of Women Voters of New York State who spent the last year and a half of her life in East Hampton with her son, Timothy Hogue Dykman, died at the age of 90 on April 14 at Southampton Hospital. She died of heart failure, her family said, but had been in declining health over the past several years, as she had Alzheimer’s disease.
She was born in Springfield, Ill., on Dec. 13, 1922, to George L. Pehlman and the former Louise Forestine Smith. A graduate of MacMurray College in Jacksonville, Ill., with a degree in art, she worked as a draftsman on the Manhattan Project in Oak Ridge, Tenn., during World War II. It was there that she met her future husband, Milton Dykman, who was a mechanical engineer on the project.
After the war, the couple moved to Rochester, N.Y. In addition to her League of Women Voters work, she was a member of the judicial nominating committee for the New York State Supreme Court and of the state’s medical quality assurance board. She was a trustee of the Rochester Institute of Technology.
An artistic person who had a bumper sticker on her car that said, “Question Authority,” she was a painter and made hand-pressed books. She enjoyed collecting art and antiques.
Besides her son, she is survived by a brother, George L. Pehlman III of Memphis, Tenn., and two grandchildren.
Ms. Dykman was cremated. A memorial service will be held in her honor at a date to be announced.
