    Penicillin research and production are depicted in this painting by Robert A. Thom, commissioned by Parke, Davis & Company as part of their “Great Moments in Pharmacy” advertising campaign in the 1950s.

  • Magazine page featuring an illustration of a military field medic administering an injection in the arm of a soldier lying on the ground.

    Advertising played a role in establishing the image of penicillin as the wonder drug.

  • Drawing of strands of Penicillium mold as they appear through a microscope.

    “Growing in a liquid medium, this mold gives out golden droplets rich in penicillin—but the liquid must be concentrated over 30,000 times to obtain pure penicillin.”

  • Two women in surgical gowns, masks, and head coverings in a room stacked with square ceramic penicillin vessels.

    Six “Penicillin Girls” nurtured the growing mold and harvested the penicillin from the hundreds of culture vessels at the manufacturing operation established at Oxford University in 1940.

  • Square-sided, flat ceramic vessel with short cylindrical spout near one corner shown from the top and side.

    Unable to establish large-scale commercial production, the British turned to the United States in 1942. More than twenty American drug companies joined the U.S. government’s penicillin production effort. Industrial fermentation tanks replaced small vessel production and by 1944 penicillin supplies met military needs.

  • Title page of Yellow Magic featuring the title in a yellow rectangle.

    The publication of Yellow Magic: The Story of Penicillin in 1945 celebrated the achievement of the American drug companies engaged in penicillin production.

  • Pharmacetical booklet cover with a photograph a vial and graphic illustrations of drug stores.

    In April 1945, the American Pharmaceutical Association published a special penicillin issue to educate retail pharmacists about the new drug. Companies engaged in penicillin manufacture used the opportunity to promote their brand and stake a claim in the expanding market.

  • Clear plastic envelope containing a sample of dirt and a paper card with blue ink handwriting.

    Soil, naturally rich in microbial life, became an important source for antibiotic discovery. The Pfizer company alone tested over 100,000 soil samples from around the world, as drug companies competed to develop new products. This envelope of soil, from a cornfield in the Midwest, yielded a winning microbe and led to a successful new antibiotic named Terramycin.

  • Magazine ad featuring a photograph of a hand grabbing dirt and particles spilling out back onto a beach.

    The Parke Davis company tested thousands of soil samples each year for new microorganisms. Advertisements in popular magazines highlighted the enormous research effort required to produce one or two useful products.

  • Box, bottle, and dispensing cup for oral antibiotic product.

    New penicillins, such as ampicillin (brand name Polycillin) developed in the 1960s, were effective for treating many common infections. Oral formulas made taking the medicine more convenient. Doctors and patients came to rely on antibiotics even in uncertain diagnoses.

  • Boxes and bottles of livestock antibiotic products with pictures of a pig, a chick, and eggs.

    Antibiotics provided livestock producers with a means to control the infections that spread quickly through large herds and feed lots. After researchers discovered that these antibiotics had the side effect of promoting growth, drug companies developed low-dose antibiotic products that could be added to the daily feed.

  • A piglet in a mesh cage drinking milk from a plastic spout as milk runs down its chin.

    Meat production and consumption expanded rapidly along with the prospering American economy in the years following World War II. This advertisement from the American Meat Institute emphasizes the benefits of meat for human health, the economy, and soil conservation.

  • Infographic on how penicillin was made.

penicillin iconMicrobes are equipped with defense mechanisms to help ensure their survival. Penicillium, the bluish-green mold that grows on stale food, produces a substance that has the power to kill its bacterial competition. Many of these bacteria are also deadly to humans.

In the years leading into World War II, British scientists established the life-saving potential of Penicillium’s natural antibiotic. Prompted by the war emergency, the United States government teamed with drug companies to mass-produce penicillin. The ability of the drug to prevent fatal infections among the wounded inspired the nickname “yellow magic.”

The anti-infective power of penicillin and other antibiotics has led to their overuse in medicine and agriculture, resulting in the emergence of drug-resistant bacteria that threaten human health.
