Dr. Bernard Andrew Brann, 84, a retired dentist in Leesburg, who was active in professional and civic organizations, died Sept. 12 at the Loudoun Memorial Hospital in Leesburg following a stroke.

Dr. Brann, who was born in Northumberland County, Va., graduated from the University of Richmond and later was a school teacher and principal. He then earned a dental degree at the Medical College of Virginia Dental School.

He established his practice in Leesburg in 1934 and continued it until his retirement about 1934.

Dr. Brann was a founder of the Virginia Society of Dentistry for Children and the Loudoun County Dental Society, a fellow of the American College of Dentists and a former chairman of its Virginia section, a fellow of the Virginia State Dental Association, which gave him its Distinguished Service Award, a member of the International College of Dentistry and a former chairman and member of the Virginia State Board of Dental Examiners.

Dr. Brann also was a former member of the Loudoun County School Board. He was a Mason, a Shriner, a charter member of the Leesburg Lions Club and a member of the Leesburg Baptist Church.

His wife, the former Bertha Oberby, died in 1977.

Survivors include two daughters, Rae B. Wine of Arlington and Leta Sue Brady of Cork City, Ireland; two sisters, Susie Sommers of Alexandria and Ruth Keckler of Palm Harbor, Fla.; two brothers, William C. of South Boston, Va., and Raymond E. of Callao, Va., and 10 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Gibeon Baptist Church, Village, Va.
