Harvey Cushing: The Artist
Cushing was a pioneer of brain surgery but contributed to many other areas. He promoted the use of x-rays in surgical practice. He discovered that pituitary is the master hormone gland and founded the clinical specialty of endocrinology. Cushing also described increased secretion of the adrenocorticotropic hormone, called Cushing's disease now.
