William Talbot Mosenthal was born in New York in 1916. He graduated from Dartmouth College in 1938. He received his medical education from and completed his residency at Cornell University. Mosenthal served in the Pacific Theater, including Iwo Jima, of World War II with the Army Medical Corps. After his military service, he returned to Dartmouth College where he worked as a surgeon at Mary Hitchcock Memorial Hospital, a professor in the Dartmouth Medical School, and as a consultant for the Veterans Affairs hospital. One of Mosenthal’s greatest achievements is his origination of the concept of the intensive care unit, establishing the first of its kind at Mary Hitchcock Memorial hospital in 1955. Although retiring as a practicing surgeon in 1981, Mosenthal continued to serve as a full-time professor in the Dartmouth Medical School until 2002. Mosenthal authored three medical textbooks, contributed to more than two dozen medical journal articles, and frequently spoke at medical conferences. In recognition of his achievements as a professor of medicine and his contribution to the medical field, Mosenthal received the Basic Science Teaching Award three times. In his honor, Dartmouth Medical School students created the Dartmouth-Mosenthal Surgical Society in 1995. Mosenthal died on November 26, 2003.
