Rabbi Seymour Spolter, 39, an attorney with the Federal Energy Regulatory Commission and a Talmudic scholar, died of cancer Dec. 10 at his home in Silver Spring.

Rabbi Spolter, who was born in New York City, grew up in Miami Beach, Fla. He graduated from Yeshiva University in New York City in 1963 and was ordained a rabbi at Mesifta Tifereth Jerusalem in New York in 1965. He took his law degree at New York University in 1968.

In the same year, he went to work for the Securities and Exchange Commission in New York. In 1973, he transferred to the agency's Washington headquarters. In 1977, he joined the Department of Energy. He had been with the FERC since 1978.

Rabbi Spolter taught at the Midrasha Community Hebrew High School in Silver Spring. He also was a member of the board of the Young Israel Shomrai Emunah in Silver Spring and of the board of education of the Hebrew Academy of Greater Washington.

Survivors include his wife, Shaine, and seven children, Sarah, Shira, Yael, Ruby, Yair, Mordechai and Yonatan, all of Silver Spring, and his parents, Mr. and Mrs. Isadore Spolter, and two brothers, Arthur and David, all of Miami Beach.

The family suggests that expressions of sympathy be in the form of contributions to the Yeshiva High School of Greater Washington, or to the Hebrew Academy of Greater Washington.
