History of Pfizer
Charles Pfizer and his cousin Charles Erhart founded Charles Pfizer and Company in Brooklyn, New York in 1849. The company's first product was santonin, an antiparasitic agent, which Pfizer made more palatable by mixing it with almond-toffee candy. This early focus on making medicines more acceptable to patients reflected a commercial instinct that would define the company.
Pfizer's first major commercial success came during the Civil War, when the company supplied large quantities of citric acid, tartaric acid, and cream of tartar to the Union Army. The company subsequently expanded into other fine chemicals and pharmaceutical ingredients.
Pfizer's breakthrough into modern pharmaceuticals came during World War II. The company developed a deep-tank fermentation process for producing penicillin in large quantities, making Pfizer the world's largest producer of penicillin by the end of the war. This manufacturing capability positioned Pfizer as a major force in the emerging antibiotic industry.
In 1950, Pfizer scientists discovered oxytetracycline (Terramycin), a broad-spectrum antibiotic. Pfizer marketed Terramycin directly to physicians, establishing the company's direct-to-physician sales model that became standard in the pharmaceutical industry.
Pfizer listed on the New York Stock Exchange in 1944. The company expanded internationally through the 1950s and 1960s, establishing subsidiaries in Europe, Latin America, and Asia.
The 1990s and 2000s were defined by blockbuster drugs and major acquisitions. Pfizer launched Viagra (sildenafil) in 1998 for erectile dysfunction, which became one of the most commercially successful drugs in history. Lipitor (atorvastatin), acquired through the 2000 merger with Warner-Lambert for approximately $90 billion, became the world's best-selling drug, generating peak annual revenues of approximately $13 billion.
Pfizer acquired Pharmacia in 2003 for approximately $60 billion, adding Celebrex and other products. The company acquired Wyeth in 2009 for approximately $68 billion, adding vaccines (Prevnar), biologics, and consumer healthcare products. Pfizer acquired Allergan's branded pharmaceutical business in 2016 for approximately $14 billion.
In 2020, Pfizer partnered with BioNTech to develop a COVID-19 mRNA vaccine. Comirnaty received emergency use authorization in December 2020 and became one of the most widely administered vaccines in history. Pfizer and BioNTech split revenues from Comirnaty, with Pfizer retaining approximately 50% of profits.
In 2023, Pfizer acquired Seagen, an oncology company specializing in antibody-drug conjugates, for approximately $43 billion. The acquisition significantly strengthened Pfizer's oncology pipeline and commercial portfolio.
For full-year 2025, Pfizer reported revenue of approximately $63.6 billion, reflecting the normalization of COVID-19 product revenues and the contribution of Seagen's oncology products.
