Samuel Gishman, 74, a retired financial analyst with the Securities and Exchange Commission who specialized in the utilities industry, died of cancer Wednesday at Washington Adventist Hospital in Takoma Park.

Two years later, he joined the World Bank, where for four years he was a financial analyst of public utility projects in Latin America.

In 1972, he returned to the SEC as chief finanacial adviser in the division of corporate regulation. He was credited by colleagues with introducing many young lawyers and analysts to utility finance. He retired in 1975. He was a resident of Takoma Park.

Survivors include his wife, the former Alma Diamond, of Takoma Park; one daughter, Vicki Felton, of Denver; one brother, Murray, of New York City; two sisters, Esther Dorn and Naomi Tepper, both of Margate, Fla., and two grandchildren.
