Ian Donald

Ian Donald was an English physician who pioneered the diagnostic use of ultrasound in obstetrics, enabling the visual discovery of abnormalities during pregnancy. Donald was born in Cornwall, England, to a Scottish family of physicians. He was educated in Scotland and South Africa before studying medicine at the University of London in 1930, and became the third generation of doctors in his family. At the start of World War II, Donald was drafted into the Royal Air Force as a medical officer, where he developed an interest in radar and sonar. In 1952, at St Thomas' Hospital, he used what he learned in the RAF to build a respirator for newborn babies with respiratory problems.
