The company’s milestones:

-In 1849 – The company was founded by Charles Pfizer and Charles Erhart in 1849 and is headquartered in New York. The business produced chemical compounds, and was headquartered on Bartlett Street in Williamsburgh, New York, where they produced an antiparasitic called santonin. This was an immediate success, although it was production of citric acid that led to Pfizer’s growth in the 1880s.

– In 1881 – Pfizer moved its administrative headquarters to 81 Maiden Lane in Manhattan, presaging the company’s expansion to Chicago, Illinois a year later.

– In 1900 – The company was incorporated in New Jersey as Charles Pfizer & Company Inc.

– In 1919 – World War I caused a shortage of calcium citrate, which Pfizer imported from Italy for the manufacture of citric acid, and the company began a search for an alternative supply. Pfizer chemists learned of a fungus that ferments sugar to citric acid, and they were able to commercialize production of citric acid from this source in 1919.

– In 1938 – Pfizer pushes ahead in 1938 with production of vitamin B-2, or riboflavin, and eventually develops a vitamin mix that includes riboflavin, thiamin, niacin, and iron.

– In 1944 – Mass production began in 1944, when Pfizer penicillin arrived with the Allied forces on the beaches of Normandy on D-Day.

– In 1950 – Due to price declines for penicillin, Pfizer searched for new antibiotics with greater profit potential. Pfizer discovered oxytetracycline in 1950, and this changed the company from a manufacturer of fine chemicals to a research-based pharmaceutical company.
