Norman Bliss Jacobs Jr., 64, a native of Gaithersburg and the vice president of a building supply firm in Eugene, Ore., died July 23 at the Eugene Hospital and Clinic. He had diabetes.

Mr. Jacobs graduated from Gaithersburg High School, attended the University of Maryland and earned a bachelor's degree at American University. He later worked for the YMCA and American Airlines in Washington.

During World War II, he was a lieutenant in the Naval Air Transport Service and was stationed in Rio de Janeiro, Brazil. He remained there after the war and engaged in the import-export business.

In the early 1950s, he returned here and became the manager of the Gaithersburg Farmers Supply Corporation, a family business. In the mid-1950s, he moved to Visalie, Calif., where he was in the aluminum storm window business. About 1971, he moved to Eugene and became vice president and product manager for residential window sales for Empire Pacific Industries.

Survivors include his wife, the former Virginia Woolman, of Eugene; two daughters, Catherine Jacobs of Fresno, Calif., and Patricia Hansen of Visalia, and one brother, Dr. James W. Jacobs of Gaithersburg.

The family suggests that expressions of sympathy be in the form of contributions to the American Diabetes Association, 4405 East-West Highway, Bethesda, Md.
