The pioneering scientists who worked in elemental chemistry weren’t thinking about poisons in particular. But others were. In 1814, in the midst of this blaze of discovery, the Spanish chemist Mathieu Orfila published a treatise on poisons and their detection, the first book of its kind. Orfila suspected that metallic poisons like arsenic might be the easiest to detect in the body’s tissues and pushed his research in that direction. By the late 1830s the first test for isolating arsenic had been developed. Within a decade more reliable tests had been devised and were being used successfully in criminal prosecutions.
But the very science that made it possible to identify the old poisons, like arsenic, also made available a lethal array of new ones. Morphine was isolated in 1804, the same year that palladium was discovered. In 1819 strychnine was extracted from the seeds of the Asian vomit button tree (
Strychnos nux vomica
). The lethal compound coniine was isolated from hemlock the same year. Chemists neatly extracted nicotine from tobacco leaves in 1828. Aconitine—described by one toxicologist as “in its pure state, perhaps the most potent poison known”—was found in the beautifully flowering monkshood plant in 1832.
And although researchers had learned to isolate these alkaloids—organic (carbon-based) compounds with some nitrogen mixed in—they had no idea how to find such poisons in human tissue. Orfila himself, conducting one failed attempt after another, worried that it was an impossible task. One exasperated French prosecutor, during a mid-nineteenth-century trial involving a morphine murder, exclaimed: “Henceforth let us tell would-be poisoners; do not use metallic poisons for they leave traces. Use plant poisons . . . Fear nothing; your crime will go unpunished. There is no corpus delecti [physical evidence] for it cannot be found.”
So began a deadly cat and mouse game—scientists and poisoners as intellectual adversaries. A gun may be fired in a flash of anger, a rock carelessly hurled, a shovel swung in sudden fury, but a homicidal poisoning requires a calculating intelligence. Unsurprisingly, then, when metallic poisons, such as arsenic, became detectable in bodies, informed killers turned away from them. A survey of poison prosecutions in Britain found that, by the mid-nineteenth century, arsenic killings were decreasing. The trickier plant alkaloids were by then more popular among murderers.
In response, scientists increased their efforts to capture alkaloids in human tissue. Finally, in 1860, a reclusive and single-minded French chemist, Jean Servais Stas, figured out how to isolate nicotine, an alkaloid of the tobacco plant, from a corpse. Other plant poisons soon became more accessible and chemists were able to offer new assistance to criminal investigations. The field of toxicology was becoming something to be reckoned with, especially in Europe.
The knowledge, and the scientific determination, spread across the Atlantic to the United States. The 1896 book
Medical Jurisprudence, Forensic Medicine and Toxicology,
cowritten by a New York research chemist and a law professor, documented the still-fierce competition between scientists and killers. In one remarkable case in New York, a physician had killed his wife with morphine and then put belladonna drops into her eyes to counter the telltale contraction of her pupils. He was convicted only after Columbia University chemist Rudolph Witthaus, one of the authors of the 1896 text, demonstrated the process to the jury by killing a cat in the courtroom using the same gruesome technique. There was as much showmanship as science, Witthaus admitted; toxicology remained a primitive field of research filled with “questions still unanswerable.”
IN THE EARLY TWENTIETH CENTURY industrial innovation flooded the United States with a wealth of modern poisons, creating new opportunities for the clever poisoner and new challenges for the country’s early forensic detectives. Morphine went into teething medicines for infants; opium into routinely prescribed sedatives; arsenic was an ingredient in everything from pesticides to cosmetics. Mercury, cyanide, strychnine, chloral hydrate, chloroform, sulfates of iron, sugar of lead, carbolic acid, and more, the products of the new chemistry stocked the shelves of doctors’ offices, businesses, homes, pharmacies, and grocery stores. During the Great War poison was established as a weapon of warfare, earning World War I the name “The Chemist’s War.” And with the onset of Prohibition a new Chemist’s War raged between bootleggers and government chemists working to make moonshine a lethal concoction. In New York’s smoky jazz clubs, each round of cocktails became a game of Russian roulette.
There was no way for the barely invented science of toxicology to keep up with the deluge. Though a few dogged researchers were putting out manuals and compiling textbooks on the subject, too many novel compounds had yet to be analyzed and most doctors had little or no training in the subject.
IN 1918, HOWEVER, New York City made a radical reform that would revolutionize the poison game and launch toxicology into front-page status. Propelled by a series of scandals involving corrupt coroners and unsolved murders, the city hired its first trained medical examiner, a charismatic pathologist by the name of Charles Norris. Once in office, Norris swiftly hired an exceptionally driven and talented chemist named Alexander Gettler and persuaded him to found and direct the city’s first toxicology laboratory.
Together Norris and Gettler elevated forensic chemistry in this country to a formidable science. Trailblazing scientific detectives, they earned a respected place in the courtroom, crusaded against compounds dangerous to public health, and stopped a great many Jazz Age poisoners in their tracks. As they determinedly countered the obstacles faced in each new case they developed innovative laboratory methods for teasing toxins from human tissue. Their scientific contribution became a legacy for future generations.
But this story begins before Charles Norris or Alexander Gettler took office, before forensic toxicology was considered a fully legitimate science. It begins in the gray of a frozen January in the city, when an unlikely serial killer decided to make his move in the poison game.

T WOULD, OF COURSE, be in the cursed winter of 1915—when ice storms had glassed over the city, when Typhoid Mary had come sneaking back, when the Manhattan coroner was discovered to be skunk-drunk at crime scenes—that the loony little porter would confess to eight poison murders.
At first the confession seemed just more of the general craziness spiking across the city. New York was mired in winter, horse-drawn carriages careening through snow-drifted Broadway, trolleys stuck in place from the Bronx to Coney Island as the weight of ice dragged down the lines. The streets commissioner had hired fifteen thousand “snow fighters,” as he called them, to dig out the roadways. Even as the fighters shoveled and chopped, new snow dropped, new sleet kept falling, laying down yet another treacherous layer.
During those same days of darkening skies and frozen streets, public authorities were desperately trying to stop a sudden outbreak of typhoid fever. The city’s most notorious carrier, Typhoid Mary Mallon, had violated the conditions of her release from a sanitarium and gone to work as a cook at a local hospital. Twenty-five people were sick and two dead before they managed to hunt her down and take her—screaming and cursing them for persecution—back into custody.
THE CITY’S coroner had been no help in that investigation, if indeed he ever was.
Instead, Patrick Riordan was trying to fast-talk himself out of charges that he showed up for work sodden drunk. Or as one angry witness put it, he stumbled into a death scene with “a glassy eye and smirky face” to sneer at bodies. That indictment followed an accident on the Ninth Avenue Elevated, the crowded commuter line run by the private Interborough Rapid Transit Company.
The collision had occurred several weeks earlier, in the last days of December. Newspapers described it like a scene from a circle of hell—brakes failed on a local, metal and flame exploded as it went slamming into the back of an express waiting at the Eighth Avenue and 116th Street station. The impact had pushed the wooden cars upward into a blazing pyramid. Flying sparks then set the platform on fire. Passengers, dazed and bloody, fled to the street, stumbling down the rickety stairs from the seventy-five-foot-high track, crowds gathering in the fire-lit dark to catch them if they fell. Two train workers died in the crash. Dozens more workers and passengers went to the hospital seeking treatment for burns, lacerations, and shock.
The papers also offered a memorable image of the coroner that night. Eight hours after the accident, as the hands of the clock were just slipping past two a.m., Riordan finally ambled into the police station where the bodies lay. An assistant was holding him upright, officers reported, and he was a big enough man that his weight pulled both of them sideways. Riordan looked down at the dead men. When told their names—Joseph Collins, 52, Gottlieb Minnick, 27—he snapped, slurring the words but saying clearly enough: “It’s a shame that two such names should pull us out on a night like this.” All this according to the notes of journalists covering the accident, who helped trigger a formal investigation of Riordan’s work.
Naturally it would be then, in January 1915, in the month of the drunken coroner, of snow fighters in the streets and cholera in the sick wards, that a self-proclaimed serial killer would walk into the district attorney’s office, offering up his impossible tale of poison and murder.
FREDERIC MORS was a small man, short, thin, nervous. He had narrow blue eyes, slightly shaggy dark hair, and a beard dusted with cigarette ash. He smoked constantly, those aromatic Egyptian cigarettes, and he paced, paced, paced as he told his story. He was a recent immigrant from Vienna, and his English was slow, stumbling enough, that the police brought in an interpreter. “Oh, I wish I spoke English better,” he exclaimed during the initial police interview, but the officers were able to piece together the story anyway.
He’d come over from Austria in early 1914, wanting to work in medicine. He’d found a job as an orderly at the German Odd Fellows home in Yonkers. The home, a refuge for 250 foundlings and one hundred elderly pensioners, paid only a little—$18 a month plus room and board—but allowed Mors to practice his medical interests. He was soon “made practically a nurse because the men over me realized that I knew something about nursing and was better educated than most orderlies.” Shortly later, he said, the superintendent asked him to take on another job, to help with the “removal” of some of the sickliest, and costliest, residents.
In the interview room, Mors shrugged, lit another cigarette, and continued. The superintendent was a bully, he’d realized, and it was best to do what the man wanted. But this assignment, he explained carefully, didn’t particularly bother him. “It was really a kind-hearted thing to do. They were all in great pain that could not be relieved. There was no chance for them. Also they were not pleasant physically or mentally to themselves or anyone else.” The only challenge was deciding how to carry out the assignment. After reviewing the possibilities, he decided that poison was the obvious answer. In a place where people were old and unwell, it would be easy enough to make it look as if their time had simply come.
The home’s nursing dispensary held a witch’s closet of poisons, watched over by one of the young orphans, earning her keep. There were bottles filled with sugar of lead, those silvery crystals used to treat skin rashes; painkillers such as codeine, morphine, and powdered opium; atropine, an extract from the nightshade plant, for speeding up a slowing heart; sweet-scented chloroform for anesthesia; white, powdery arsenic, for curing everything from syphilis to psoriasis; strychnine for energy tonics; and mercury for infections. The only question was which would best suit his purpose.
Mors first tried arsenic, but the elderly man selected for the experiment did not die in an orderly fashion. He was messily sick, then developed a kind of creeping paralysis, living on for several miserable days. Mors found himself on constant, exhausting nursing duty. It was horrible, he said, both for the victim and for himself. They buried the man—whatever his name was, he didn’t remember—with great relief.
He went back to the dispensary. It was, maybe, the smell that decided him, that sweet chemical sting in the air, that sugary, seductive promise. He smiled at the detectives and told them why he’d been so pleased with his next choice: “When you give an old person chloroform, it’s like putting a child to sleep.”
