Raymond Joseph Simon, 62, an account executive with Bache Halsey Stuart Shields Inc., an investment firm here, died Thursday at George Washington University Hospital after a heart attack.

He had been with the company for 10 years. Before that he had worked as a real estate broker and at different times had owned his own firms, Simon and Frank in Silver Spring and Colonial Realty in Arlington.

Mr. Simon was born in Washington and was a lifelong resident of this area. He graduated from McKinley High School and National Law School. He was a member of the D.C. Bar.

During World War II, he served as a civilian, coordinating special services for the War Department.

He was a member of the Progress Club and the Samuel Gompers Lodge of the Masons.

He is survived by his wife, Lee Ann, of the home in Silver Spring; a son, Neil J., of Potomac; three daughters, Annette R. Simon, of Santa Ana, Calif., Sheryl T. Manning, of Bowie, and Melissa B. Berkelhammer, of Silver Spring; his mother, Lillian Krupsaw, of Rockville; a sister, Izetta Magazine, of Washington, and four grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.
