John H. Lawrence

John H. Lawrence was a pioneering American physician and scientist known for developing the field of nuclear medicine. He utilized radioactive isotopes to diagnose and treat diseases, especially cancer, by tracking how substances move within the body. As a graduate of Harvard and Stanford, and the brother of Nobel laureate Ernest Lawrence, he applied innovative techniques to medicine, establishing the use of radioactive tracers to better understand health conditions. His work laid the foundation for modern diagnostic imaging and targeted cancer therapies, significantly advancing medical science and patient care.
