Trenton Psychiatric Hospital

Dr. Henry Cotton pulled 11,000 teeth and performed 645 surgeries to cure mental illness at Trenton Psychiatric. Visitors still see his white coat.

Dr. Henry Cotton pulled more than 11,000 teeth from patients at the Trenton Psychiatric Hospital, most of them without anesthesia or consent, because he believed mental illness was caused by infected tissue. When the teeth didn't cure anyone, he moved on to tonsils, gallbladders, spleens, stomachs, sections of the colon, testicles, and ovaries. His staff performed at least 645 major surgeries. The death rate was catastrophic. Cotton himself, who ran the hospital from 1907 to 1930 and stayed on until his death in 1933, is the ghost visitors report most often, still making rounds in a white doctor's coat.

The hospital opened on May 15, 1848, as the first public mental institution in New Jersey. Its founder was Dorothea Lynde Dix, one of the most important 19th-century advocates for humane mental health care. The building followed the Kirkbride Plan, an architectural theory that tried to aid recovery through patient privacy, natural light, and structured routines. For its first sixty years the Trenton asylum was considered progressive. Then Cotton arrived.

He had a theory, which was wrong, and the institutional authority to act on it, which was the problem. His theory was called focal infection. Cotton believed bacteria lodged in the body caused every form of mental disturbance, and that the cure was to find the bacteria and cut it out. He focused particularly on what he called the right side of the hindgut, which he identified as the source of depraved impulses. He removed parts of it from patients surgically. He publicized cure rates of 85 percent. Internal reviews at the hospital, conducted by statisticians who actually counted the bodies, showed that patients died on his operating tables at alarming rates and that his "cures" were unverifiable. Antibiotics did not yet exist. Surviving Cotton's care was a matter of luck.

Cotton died in 1933. Elements of his approach kept going at the hospital for decades after that, which is the part most accounts of the Trenton Psychiatric Hospital gloss over quickly. The suffering he inflicted on thousands of patients across his tenure is what people mean when they say the building has something left in it.

Explorers who have gotten into the abandoned wings describe unseen hands touching them in hallways, figures moving through doorways where there shouldn't be anyone, temperature drops that hit on the stairwells, and the feeling that someone is standing behind you in the stairwell. Besides Cotton, witnesses describe patient spirits with missing limbs or incomplete bodies, which tracks disturbingly well with what Cotton actually did to them. Screams and moans come from patient rooms that have been empty for years.

The hospital is still operating. Around four hundred beds are active in the newer sections. But the older Kirkbride wards, the wings that housed Cotton's patients, are abandoned. Their windows are dark. Their floors are collapsing in places. They are accessible only to people willing to walk where thousands of people were mutilated by a doctor who was sure he was saving them.

The Trenton Psychiatric Hospital's ghost story isn't a mystery. The building contains the documented suffering of the people Cotton experimented on, and it contains Cotton himself, still working. The question isn't what happened here. It's how many of his patients never got a proper accounting, and how many are still waiting for one.
