Born 27 Dec 1910; died 19 Jun 1987 at age 76.
A British doctor who first succeeded in using reflective ultrasound images for medical diagnosis. He was familiar with sonar during World War II and first ultrasonically probed an organ on July 21, 1955, when he was examining a tumor sample from a human organ with an industrial ultrasonic metal failure locator. I tested the idea. After a period of development, he later used ultrasound to make a life-saving diagnosis of a large, easily removable ovarian cyst in a woman who was diagnosed with unresectable gastric cancer by another patient. He published a pulsed ultrasound examination of the abdominal mass in The Lancet (7 June 1958). The following year, he expanded its use to study fetal growth during pregnancy.
