Warren probably commissioned and is featured in several daguerreotypes of operations using ether.
Physician John Collins Warren (1778-1856) assumed the Hersey Professorship of Anatomy and Surgery at Harvard Medical School in 1815. Along with James Jackson, he was a founder of the first medical journal in New England as well as of Massachusetts General Hospital, where he served as the first surgeon. He was also the first dean of the Harvard Medical School. He donated his collection of anatomical and pathalogical specimens to the school in 1847, forming the Warren Anatomical Museum. In 1846, he introduced the use of ether in surgical operations. Warren's support for -and willingness to sponsor public demonstrations of-the new procedure led to its adoption by the profession.
