Pfizer

Charles Pfizer · 1849

Pfizer wasn’t built to cure disease — it was built to ferment sugar, then scaled that trick into antibiotics.

Pfizer’s origin story is not about curing disease — it is about solving chemical supply problems with fermentation. Its therapeutic dominance came decades after it mastered industrial microbiology under pressure.

Chapters & takeaways4
  1. 1:05
    Flavourings First

    Pfizer began as a Brooklyn chemistry shop selling food flavourings and iodine — not drugs.

  2. 2:18
    Fermentation by Necessity

    A WWI citric acid shortage forced Pfizer to invent fungal fermentation — and master it.

  3. 3:33
    Penicillin at Scale

    That same fermentation skill let Pfizer mass-produce penicillin during WWII — the first industrial-scale biomanufacturing of an antibiotic.

  4. 5:07
    Early Scale

    By 1906, sales exceeded $3 million — proof the model worked before medicine dominated its identity.

The written brief1 min read

What the company or idea is

Pfizer is a multinational pharmaceutical and biotechnology corporation founded in 1849 in Brooklyn by Charles Pfizer and Charles F. Erhart.

How it actually makes money

Pfizer makes money by developing and producing medications and vaccines across immunology, oncology, cardiology, endocrinology, and neurology — but its early revenue came from food flavourings, iodine preparations, citric acid for soft drinks, and santonin.

What works

Its ability to industrialise biological processes — first citric acid using fungal fermentation by 1919, then penicillin via deep-submergence fermentation in WWII — created scalable production where others could not.

What does not

The company did not begin as a therapeutic innovator. Its founding products were industrial chemicals and food additives — not medicines — and its pivot to antibiotics was opportunistic, not premeditated.

What to take from it

Capability follows constraint: Pfizer’s fermentation mastery emerged from wartime shortages, not R&D strategy. Its business model evolved through applied chemistry, not clinical insight.

Is it worth your time

Yes — as a case study in how fermentation expertise, built to solve supply-chain shocks (citric acid in WWI, penicillin in WWII), became a durable industrial capability that shaped therapeutic scale.

Air Canada1937Air Canada is Canada’s state-founded, privatised, hub-based flag carrier—large by fleet and passengers, anchored in Montreal, Toronto, and Vancouver, and embedded in Star Alliance. It carried 45.3 million passengers in 2025. It was founded in 1937 as Trans-Canada Air Lines, renamed in 1965, privatised in 1988, acquired Canadian Airlines in 2000, and filed for bankruptcy protection in 2003 before emerging in 2004.

Air France1933Air France is the French flag carrier, formed on 30 August 1933 via merger of five airlines. It operates from Charles de Gaulle Airport, served 201 destinations across 78 countries as of 2013, and held a politically critical role in West Berlin from 1950 to 1990. Since 2003, it has been a subsidiary of Air France–KLM — not an independent entity. Its revenue comes from scheduled passenger and cargo services. Its longevity reflects state support and geopolitical utility, not market resilience or innovation.
