Dr. Aubrey D. Fischer, 81, a retired ear, nose and throat specialist in Washington, died Tuesday at Sibley Memorial Hospital. He had a heart ailment.

Dr. Fischer had established a private practice in otolaryngology here in the late 1920s and maintained it until retiring in 1958.

He was born in Alexandria and grew up in Washington.

He graduated from the George Washington University medical school, interned at the old Emergency Hospital and took his residency at the old Episcopal Ear, Nose and Throat Hospital. They later became part of Washington Hospital Center.

Dr. Fischer was with Johns Hopkins Hospital in Baltimore in the mid-1920s. He interrupted his private practice here in 1932 to take further studies in Vienna, Austria.

A former chief of Otolaryngology at Episcopal Hospital, he held the same position at Washington Hospital Center. He also had been on the staff of Children's Hospital.

Dr. Fischer was a member of the American Academy of Otolaryngology and the D.C. Medical Society and a fellow of the American College of Surgeons. He belonged to Washington Hebrew Congregation and Woodmont Country Club.

He is survived by his wife, Josephine, of the home in Washington; a daughter, Audrey DeYoung of Washington, two grandchildren and four great-grandchildren.
