Dr. Henry Simmons Murphy, 75, an obstetrician, gynecologist and surgeon in Falls Church for more than 30 years, died Feb. 2 after a heart attack while visiting at the home of a daughter in Washington.

Dr. Murphy, who lived in Great Falls, began a medical practice in Falls Church about 1945. Before that he had been a physician in Brooklyn, N.Y., and Chicago, and had a practice in Wisconsin. He also had been a physician in the Royal Canadian Air Force Medical Corps.

He was born in Lachute, Quebec, and earned a medical degree in 1928 from Queens University in Kingston, Ontario.

During his more than 50 years as a practicing physician, Dr. Murphy delivered more than 8,000 babies.

He and his wife, Alice Wilson Murphy, who died in 1976, were responsible for introducing the Tibetan terrier breed to this country in 1956. In 1957, they founded the Tibetan Terrier Club of America, which was recognized by the American Kennel Club in 1973.

In 1978, he received the City of Falls Church Certificate of Appreciation for his contributions to the community. That year, he also was honored by the Medical Society of Virginia "for 50 years of devoted service to the public in the practice of medicine."

His professional memberships included the Northern Virginia Obstetrical Society and the American Medical Association.

Dr. Murphy was a 33rd degree Mason and a member of Temple Lodge No. 64.

Survivors include two daughters, Patricia Suzanne, of the home in Great Falls, and Mary Louise Walton, of Washington; a sister, Patricia Dennis, of Mississauga, Ontario, and seven grandchildren.
