Arthur S. Feld, 59, senior partner in the law firm of Bulman, Goldstein, Feld, Dunie & Freeman, died of a heart attack Sunday at Suburban Hospital in Bethesda.

A trial lawyer, Mr. Feld began the private practice of law in 1955 with Joseph D. Bulman and Sidney M. Goldstein in an association that evolved into the present firm. During the early 1950s, he was an attorney for the Federal Communications Commission.

Mr. Feld was born in New York City and earned a bachelor's degree from New York University in 1939. After serving in the Army Air Corps during World War II, he earned a law degree from the old National University Law School, now a part of George Washington University.

He was an adjunct professor of law at Catholic University in 1972. He also was a member of the Montgomery County and Maryland State Bar Associations and served as chairman of the Montgomery County Association's Interprofessional Committee and as a member of the Maryland State Bar's Committee on Pattern Jury Instructions.

In addition, he was a fellow of the American College of Trial Lawyers, a member of the D.C. Bar Association and the American Bar Association.

He lived in Bethesda and was an active member of the Beth El Congregation of Montgomery County.

Survivors include his wife, Flora, of the home; three sons, Alan S., of Chevy Chase, Barry C., of Minneapolis, and Dr. Jeffrey E., of Mount Vernon, Wash.; a brother, Morris, of Silver Spring, and a sister, Syde Geller, of Riverside, Calif.

The family suggests that expressions of sympathy be in the form of contributions to the Arthur S. Feld Memorial Fund, c/o the Beth El Congregation, Bethesda.
