Genius on the Edge: The Bizarre Double Life of Dr. William Stewart Halsted Read Online Free PDF Page A

pass their final examinations at the completion of the third year. Clinics, where students could observe doctors treating patients, were available but not required and so were infrequently attended.
    Inadequate as this education was, Physicians and Surgeons was a cut above most medical schools across the country. Increasingly, schools like Physicians and Surgeons in New York and the Harvard Medical School in Boston were attempting to take science and education more seriously, but there was no consensus, no model to emulate, and they were struggling to find their way. The bacterial basis for disease was becoming clear, but most physicians were unwilling to abandon the faith of Hippocrates in the mystical balance of humors. Scientists were in the minority, and medicine was being taught largely as it had been for centuries.
    Despite the dismal system that he entered, Halsted managed to ferret out the best teachers and role models. Each student at Physicians and Surgeons was assigned to a preceptor from among the faculty who would serve as his mentor. The mentoring was spread thinly, as mentors would oversee several students in each of three classes. It was up to the student to make the best of the opportunity. Halsted registered with Henry B. Sands, a surgeon and professor of anatomy, the subject that had sparked his initial interest in medicine.
    From the beginning Halsted spent a great deal of time in the dissecting lab, both learning from Sands and doing his own work. Dexterous and diligent, he quickly became expert in the eyes of his fellow students and stood well above the others in the eyes of his preceptor. Sands took the opportunity to shift some of the demonstration and preparation work to his student.
    John C. Dalton, whose textbook had inspired Halsted in his extracurricular reading at Yale, was also on the faculty at P&S. Dalton’sinterests were wide-ranging, and he studied everything from localization of brain functions to the physiology of digestion. The work itself was important, but Dalton’s maverick scientific approach was a groundbreaking example of the experimental model. His students were taught to perform animal and human experiments and observe the physiological responses to stimuli. Traditionally, instructors would simply tell students what the expected response would be. Dalton taught the students to stimulate a muscle, measure the response, and learn cause and effect. This method would become the model for medical teaching in the future, and it made a lasting impression on young Halsted. He began spending increasing portions of his day in the physiology laboratory, ultimately becoming Dalton’s primary assistant and an expert in the use of the experimental model.
    It was a perfect beginning. In the nurturing hands of Dalton and Sands, Halsted was excited by his work. Attending lectures, reading, and doing dissections with Sands and experiments with Dalton was a full load, but he was energized by the demands. Intentionally or not, Halsted had the ability to associate himself with the important figures in his world. Later in life, when roles were reversed, Professor Halsted’s radar would be finely tuned against young surgeons seeking his good graces, unfailingly cutting them off at the knees.
    In his second year at Physicians and Surgeons, he began conducting chemical tests in the office of Dr. Alonzo Clark. Clark was president of the medical school, a professor of pathology and of the practice of medicine, and the leading medical consultant in the city.
    In the summer of 1875, Halsted befriended Thomas McBride. McBride, several years his senior, was already physician-in-chief at the Centre Street Dispensary, where Halsted spent the summer working in the pharmacy learning about the potions, plasters, pills, and tonics popularly used at the time. McBride was a fun-loving, handsome man-about-town, and very successful in his practice. He earned a great deal of money and spent it lavishly, and in some
