HistoryNamed after Harvey Williams Cushing (1869-1939), who was an American surgeon and pioneering neurosurgeon of the early 20th century. He received his medical doctorate from Harvard Medical School in 1895. He completed his internship at Massachussets General Hospital and went on to do a surgical residency under William Halsted at John Hopkins Hospital. He trained under Kocher in England for several years before returning stateside and setting up practice in Baltimore. One of his greatest contributions to western medicine was his introduction of blood pressure management he learned from Scipione Riva-Rocci in Italy during his time in Europe.

At the age of 32, he achieved associate professor at Johns Hopkins Hospital and was placed in full charge of all surgery of the central nervous system. In 1912, he first described what would become his eponymous disease, but before he could publish it, he was called to serve during the first world war as the director for a field hospital in France for the British. It was during this appointment that he cared for a fatally wounded soldier by the name of Lt. Edward Revere Osler, son of William Osler. He formally published his findings on his eponymous disease in 1932 in an article entitled “The Basophil Adenoma of the Pituitary Body and Their Clinical Manifestations: Pituitary Basophilism”.

During his career, he was regarded as the world’s leading teacher of neurosurgeons for in the first decades of the 20th century and held professorships at Johns Hopkins Hospital, Brigham Hospital in Boston, Harvard Medical School, Yale School of Medicine, as well as honorary Fellowship in the Royal College of Surgeons. He also was awarded the 1926 Pulitzer Prize for Biography for his biography on the life of William Osler and was nominated for the Nobel Prize in Physiology or Medicine 28 times.
