Harvey Williams Cushing (April 8, 1869 – October 7, 1939) was an American neurosurgeon. A pioneer of brain surgery, he was the first person to describe Cushing's syndrome. He is often called the "father of modern neurosurgery."
In the beginning of the 20th century he developed many of the basic surgical techniques for operating on the brain. This established him as one of the foremost leaders and experts in the field. Under his influence neurosurgery became a new and autonomous surgical discipline.
He considerably improved the survival of patients after difficult brain operations for intracranial tumors.
He used x-rays to diagnose brain tumors.
He used electrical stimuli for study of the human sensory cortex.
He played a pivotal role in development of the Bovie electrocautery tool with W. T. Bovie, a physicist.
He was the world's leading teacher of neurosurgeons in the first decades of the 20th century.
Arguably, Cushing's greatest contribution came with his introduction to North America of blood pressure measurement. On visiting colleague Scipione Riva-Rocci, an Italian physician, Cushing was astonished at Riva-Rocci's non-invasive way to measure intra-arterial pressure. In 1896, Riva-Rocci developed a wall-mounted mercury manometer linked to a balloon-inflated cuff that would measure the pressure needed to compress arterial systolic pressure, i.e. systolic blood pressure measurement. Riva-Rocci's design was based on a more primitive version developed by French physician Pierre Potain. Cushing brought back a sample of Riva-Rocci's sphygmomanometer, and blood pressure measurement became a vital sign and its use spread like wildfire across the US and western world as a direct contribution by Harvey Cushing. Its use remained until Russian physician Nikolai Korotkov included diastolic blood pressure measurement in 1905 (after he discovered the famed "Korotkoff sounds") with his modern sphygmomanometer, which also replaced the mercury manometer with a smaller, round dial manometer.
Cushing's name is commonly associated with his most famous discovery, Cushing's disease. In 1912 he reported in a study an endocrinological syndrome caused by a malfunction of the pituitary gland which he termed "polyglandular syndrome." He published his findings in 1932 as "The Basophil Adenomas of the Pituitary Body and Their Clinical Manifestations: pituitary Basophilism". Cushing was also awarded the 1926 Pulitzer Prize for Biography or Autobiography for a book recounting the life of one of the fathers of modern medicine, Sir William Osler. In 1930, Cushing was awarded the Lister Medal for his contributions to surgical science. As part of the award, he delivered the Lister Memorial Lecture at the Royal College of Surgeons of England in July 1930. Cushing was elected to the Royal Swedish Academy of Sciences in 1934, and a Fellow of the Royal Society of London. He served as president of the History of Science Society in 1934.
In 1988, the United States Postal Service issued a 45 cent postage stamp in his honor, as part of the Great Americans series.
Aside from Cushings many accomplishments, he developed many surgical instruments that are still in use today, most notably the Cushing Forcep. This instrument is used to grasp the thick tissues of the scalp during cranial surgery. He also developed a surgical magnet while working with the Harvard Medical Unit in France during World War I to extract bullets from the heads of wounded soldiers.
In 2010, Yale placed on display Cushing's collection of brain specimens. There is also a collection of his papers at the National Library of Medicine.
It's a behemoth of a book and it was the life of Osler pieced together by Cushing who went through and published many of his letters from Osler to friends and family and from others who wrote about Osler. The stories are great and it's precious to read "well, that's the 90s!" when they are referring to the 1890s. The book is broken up into the different times of Oslers life and on the top of the right pages it's a new title of what the page is about and the left is the chapter. Amazing. The book I have is from 1940 and made out to a Mr. Marland. The stories are great and learning about Dr Oslers career is very interesting because it spans his entire life from when he first was interested in medicine and when it he later had his own private practice and teaching and Hopkins, etc.
