The story of the first successful use of penicillin in the United States and how it launched the antibiotic revolution that saved millions of lives.
Imagine a world where a simple scratch from a rose thorn could lead to a death sentence. Where blood poisoning was a common and terrifying killer, and doctors had little more than hope to offer patients raging with infection. This was the stark reality before October 16, 1942—the day the medical landscape in the United States changed forever. The hero of our story isn't a person, but a molecule: penicillin. While discovered in London, it was on American soil that this "yellow magic" was first successfully used to snatch a life from the jaws of a deadly infection, launching a medical revolution that would save countless millions.
Before diving into the historic case, it's crucial to understand why penicillin was so revolutionary. For centuries, scientists had dreamed of a "magic bullet"—a drug that could hunt down and destroy disease-causing microbes inside the body without harming the patient.

First true antibiotic
In the pre-antibiotic era, even minor infections could become life-threatening. Surgical procedures carried extreme risks, and diseases like pneumonia, tuberculosis, and blood poisoning were often fatal. The discovery of penicillin marked a turning point in medical history.
Mortality rate for severe bloodstream infections before antibiotics
The first American recipient of penicillin was Anne Sheafe Miller, a 33-year-old woman from New Haven, Connecticut. Her case was not just a medical procedure; it was a desperate gamble that would determine the future of the drug.
In late February 1942, Anne was hospitalized at New Haven Hospital, dying from a severe streptococcal infection following a miscarriage. She was suffering from high, relentless fevers, severe abscesses, and was drifting in and out of consciousness. For a month, her doctors had tried everything: blood transfusions, surgery, and the best available anti-infective drugs, including sulfa drugs. Nothing worked. Her temperature chart was a grim record of a losing battle.
"This was not a planned clinical trial. It was a last-ditch effort to save a life, orchestrated by Anne's doctor, Dr. John Bumstead, who had learned of penicillin from his colleague, Dr. John Fulton."
Dr. Fulton contacted the Merck & Co. laboratory, which was one of the few places in the U.S. experimenting with penicillin production. He pleaded for any available supply.
Step 1On March 14, 1942, a small vial containing 5.5 grams of a brownish powder—the entire United States' supply of purified penicillin at the time—was rushed from Merck to New Haven. It was dissolved in a saline solution.
Step 2Because the drug was so scarce and its effects unknown, it was administered intravenously, with great care to not waste a single drop. The initial dose was given at 3:30 p.m.
Step 3Understanding that the drug would be flushed from the body quickly, the medical team administered a continuous, low-dose IV drip. For the first day, Anne received an injection every four hours.
Step 4Within hours, her fever began to drop. Her condition stabilized overnight.
Step 5After 24 hours, the team realized they had used almost all the penicillin. Anne's fever spiked again as the remaining bacteria multiplied. A frantic search began to find more of the drug. Every available source was tapped, including extracting penicillin from the patient's own urine to be purified and re-injected—a testament to the extreme scarcity.
Step 6After a total of five days of treatment, Anne's temperature returned to normal and stayed there. She was out of danger. The infection had been defeated.
Step 7The following data visualizations quantify the dramatic turnaround in Anne Miller's condition.
This chart shows the rapid and dramatic drop in the patient's fever following the initial administration of penicillin, a clear sign the infection was being controlled.
This visualization illustrates the intensive, round-the-clock effort required to maintain effective levels of the drug in the patient's system.
This chart contextualizes the success of penicillin by comparing it to the dismal outcomes associated with the best available treatments of the era.
The production of the first penicillin was a painstaking, low-tech process. Here are the key "research reagents" and materials used in its early development and in Anne Miller's treatment.
The original source organism. It was grown in culture to secrete penicillin into the nutrient broth.
A nutrient-rich liquid that fed the mold and allowed it to produce penicillin.
Large, sterile vats where the mold could be grown in massive quantities.
A solvent used to extract the crude penicillin from the culture broth.

The successful treatment of Anne Miller was more than a medical marvel; it was a turning point in human history.
It proved that the "magic bullet" was real and could be wielded against humanity's oldest microscopic enemies. The subsequent, massive government-funded effort to produce penicillin not only saved the lives of thousands of soldiers during World War II but also paved the way for the development of all modern antibiotics.
The story of that first, fragile vial of brown powder and the woman it saved is a powerful reminder of how a single, desperate experiment can change the world for generations to come.
