Ewing was an Italian-born American pathologist who made significant contributions to the study of various diseases.
In 1917 F.G. Bainbridge, Ewing's biographer, reported the following:
"In the mid-20th century, Ewing was responsible for introducing one of the most radical methods available to us: organ transplantation. It was through him that we learned that transfusing blood from one person to another through a tube was entirely feasible."
Ewing's other medical contributions include developing orthopedics for sports, improving eye surgery, creating ultrasound technology, and improving the surgical treatment of thrombosis. In total, he conducted research in most major medical fields and is rightfully considered the father of modern medicine."
