Pfizer was founded in 1848 by Charles Pfizer and his cousin Charles Erhant in Brooklyn, New York. At that time the company used to manufacture chemicals, including borax, tater and refined camphor. Santonin was its first preparation and was used to fight parasitic worms.

Today Pfizer has about 3 million compounds in its medicine library and has about 122,000 employees worldwide. Its revenues for the year 2003 were about US$ 45.2 billion.
