The William J. Fry Memorial Lecture Award was established by Joseph H. Holmes, MD, in 1969, and presented for the first time at the AIUM annual meeting in Winnipeg that year. William J. Fry, MS, was a physicist with a strong interest in ultrasound in biology and medicine, whose innovative research efforts advanced the field of diagnostic ultrasound. One of Professor Fry's most notable contributions was the successful design of an ultrasonic system used to pinpoint lesions in the brain without damaging adjacent tissues. This ultrasonic system was later used to treat various brain pathologies, and in particular, Parkinson's disease. His impassioned interest in ultrasound led him to become president of the AIUM from 1966 until his death in 1968. The following year, the William J. Fry Memorial Lecture Award, recognizing a current or retired AIUM member who has significantly contributed, in his or her particular field, to the scientific progress of medical diagnostic ultrasound, was established in his honor.
