In the last months of 1919, newspapers across the country ran a small, strange item out of San Quentin Penitentiary. The prisoners there, it said, regarded their doctor, Leo Stanley, as a "wonder worker." He had given ten inmates new "interstitial glands," the polite term of the day for testicles, taken from the bodies of executed murderers. An eleventh operation would follow the next hanging.
A peanut butcher goes to prison
Stanley was born in Oregon in 1886. His father was a country doctor, and Stanley planned to become one too. His family moved to Northern California when he was nine. He started at Stanford in 1903 but dropped out after a year to work the Southern Pacific Railroad as a peanut butcher, the name for a newsboy who sold snacks and newspapers on the train. He loved the work, and he turned out to be a natural salesman.
He went back, finished at Stanford and earned his medical degree at Cooper Medical College in San Francisco. A month before graduation he married Romaine, a secretary at the school. Interns got room and board and no pay. So in 1913, when San Quentin offered him $75 a month as resident physician, he jumped at it. At the time, medical workers averaged $500 a year or less. He meant to get some experience and then set up as a country doctor. Instead, the prison gave him something that pulled harder than house calls: a literally captive population of men on which to test his theories.
A murderer in the kitchen
Soon after they arrived, Romaine came down with tuberculosis, and her case was severe. Antibiotics were still more than 30 years away. The treatment was rest, fresh air and the best food money could buy, and oddly enough, the prison could supply all three. The couple lived in a hilltop house overlooking San Quentin, where the same sea air that blew through the cell blocks off San Francisco Bay blew through their windows. The prison assigned a convicted murderer named Lim Foon to take care of her. Stanley called him an excellent nurse and quite the cook.
With his wife cared for, Stanley threw himself into the job. Between 1913 and 1940 he supervised 150 executions. He fought tuberculosis in the crowded cell blocks. He also did plastic surgery on men about to be paroled, reasoning that a better face gave a man a better chance at a job. His work was so good that the warden started rephotographing these men before release so police could still recognize them.
Who gets to have children
Stanley had a darker side. He was a firm believer in eugenics, the movement to "improve" humanity by controlling who could have children. It bothered him that San Quentin housed races he considered undesirable alongside white Christians. Starting in 1909, California forcibly sterilized more than 20,000 people over 70 years, mostly in mental hospitals. That annoyed Stanley, who argued that one in five inmates was unfit to have children. "Sterilization, when given its chance, will do much to stamp out crime," he wrote.
His bedside manner was just as harsh. He refused to mollycoddle inmates, his word. When Dwight Myers came in with his hand crushed in a machine gearbox, another doctor ordered him rushed to the operating room. Myers remembered what happened next: "Dr. Stanley says, hell no. Put him over on the table there and get the bone clipper and get to work." Stanley did the work himself, with no anesthetic. In 1935 he put up a sign in the main yard promoting vasectomy, "the cutting of the G-string," as a boost to health and vigor.
For decades, San Quentin's doctor sewed testicles from freshly hanged murderers into living inmates, sure that a new pair could cure a man of crime.
Spare parts from the gallows
Doctors had been grafting testicles into patients since the late 1800s, sometimes using glands from goats, rams, boars or deer. Stanley was happy to use goats, but death row gave him a steady supply of human glands. Thomas Belton was hanged for murder on October 10, 1919. Within the hour, his testes were in the scrotum of a worn-out inmate serving 60 years for manslaughter. Stanley reported that within three days the man stood straighter, walked faster and laughed louder. Within five days he was back in the general population, even though his surgical wound hadn't healed.
The recipient got a spinal block, which numbed him from the waist down, and stayed awake for all of it. He watched Stanley remove his testes, then waited while Stanley cut the replacements from a body brought straight from the gallows. Stanley also mashed donor glands into a paste and injected it into patients' abdomens. He was sure it could treat acne, depression, erectile dysfunction and even pedophilia, which he blamed on old age. In his book Men at Their Worst he wrote, "Perhaps the outworn glands look for solace in strange directions."
He even believed new glands could cure a man of crime. His first transplant patient was a 25-year-old he described as a "feeble-minded moron who possessed higher intelligence than an imbecile." Seven weeks after the surgery, the man had gained 15 pounds. "I believe he is rid permanently of his criminal tendencies," Stanley said, about a man now carrying a hanged murderer's testicles. By 1937 he had done more than 6,000 transplants, and over his career he performed some 10,000 gland rejuvenation treatments. When no family claimed an executed man's body, it went to science, so the supply never ran dry. Some recipients wanted the surgery badly. Others probably just wanted a break from prison routine and the better food in his hospital ward. Word got out, and wealthy men wanted in, specifically on the glands of violent murderers. One widow was offered $10,000 for her condemned husband's testicles and turned it down: "how could I sell a piece of my husband like that?"
The party ends, and a pardon
World War II ended the experiments. Stanley left to serve as a Navy doctor. By the time he came back, Nazi war crimes had turned the public against eugenics, and California's corrections department opposed sterilization. He won a local election in Marin County in 1946, retired from San Quentin in 1951 and later worked as a ship's surgeon on a cruise line.
Romaine died of tuberculosis in 1926, but before she did, she taught Lim Foon to read and write. Lim had been arrested at 18 for a gang killing outside a poultry shop in Stockton. He had only been visiting a friend. He ran out the back and hid in a chicken coop, and police took his terror for guilt. Stanley believed Lim was innocent, paid for an investigation himself and persuaded Governor Friend Richardson to grant a full pardon. An elderly, dying man later confessed to the murder.
Stanley died in 1976 at age 90, two years after Congress passed the National Research Act to protect people used in medical research. He never faced any consequences for his experiments, and he never had a transplant himself. But his crude hunch about male hormones helped open the research into testosterone that eventually led to Viagra.
