William Williams Keen

Keen was born in Philadelphia on January 19, 1837, to William Williams Keen Sr. (1797–1882) and Susan Budd. He attended Saunders's Academy and Philadelphia's Central High School. Keen graduated from Brown University, with an A.B. in 1859. He then obtained a degree in medicine from Jefferson Medical College in 1862. ==During the American Civil War==

Keen served as a surgeon for the Fifth Massachusetts Militia Regiment and then for the Union Army during the American Civil War. While serving, Keen built a reputation for his work with patients who had neurological wounds, mainly because most surgeons refrained from treating neurological wounds. He also worked with S. Weir Mitchell to study nervous system injuries. Together, they published Gunshot Wounds and Other Injuries of the Nerves and Reflex Paralysis in 1864, which first described many unknown neurological conditions, such as causalgia, reflex sympathetic dystrophy, and secondary paralysis. After the war concluded, Keen studied in Paris and Berlin for two years. ==Career==

Keen began to teach pathological anatomy and prepared the first-ever surgical pathology course at Jefferson Medical College. He also established the school's first surgical research lab. He also taught at the Pennsylvania Academy of the Fine Arts and the Woman's Medical College of Pennsylvania. Keen was the leader of a team of five that performed a secret surgical operation to remove a cancerous jaw tumor on Grover Cleveland in 1893 aboard Elias Cornelius Benedict's yacht Oneida. Keen and four assisting doctors made their way to the yacht by boat from separate points in New York, with Cleveland and Bryant boarding in the evening for the night before sailing the next morning. With calm weather and steady waters, the surgery was finished quickly as the ship transited from Long Island Sound during noontime. The procedure involved the removal of the tumor and five teeth, as well as much of the upper left palate and jawbone. Later, Keen performed a follow-up surgery to remove excess tissue and to cauterize the wound. ==Personal life==

Keen was a theistic evolutionist; he authored the book I Believe in God and in Evolution in 1922. Keen was a staunch proponent of vivisection and wrote articles attacking the arguments of anti-vivisectionists, some of which were republished in his 1914 book, Animal Experimentation and Medical Progress. In 1867, Keen married Emma Corinna Borden, from Fall River, Massachusetts, who died in 1886. and is buried at The Woodlands Cemetery. ==Honors and recognition==

He received honorary degrees from Jefferson Medical College, Brown University, Northwestern University, University of Toronto, University of Edinburgh, Yale University, University of St Andrews, University of Greifswald, and Uppsala University. He also served as president of the American Surgical Association in 1898, the American Medical Association in 1900, the Congress of American Physicians and Surgeons in 1903, and the American Philosophical Society after 1907 (elected in 1884). When the International Surgical Association met in 1914, he was elected president for the meeting in 1917. After 1894, he was a foreign corresponding member of the Société de Chirurgie de Paris, the Société Belge de Chirurgie, and the Clinical Society of London as well as an honorary fellow of the Royal College of Surgeons of England, the Royal College of Surgeons of Edinburgh, the German Society of Surgery, the Palermo Surgical Society, and the Berliner Medizinische Gesellschaft. He was also made an associate fellow of the American Academy of Arts and Sciences. ==Things named after him==
