Pfizer is currently the largest drug and pharmaceutical corporation in the world. The company began in 1849 to produce chemicals for use in pharmaceutical manufacturing. This experience as a company was invaluable to the war effort in the Second World War, as it gave Pfizer the expertise to become a producer of newly developed antibiotics in the 1940's [12]. The extreme wartime demand for penicillin drove the company to expand and diversify into related fields rapidly, and the company produced half of the world’s antibiotics by 1945 [12]. The company then became a conglomerate, producing everything from diapers to over-the-counter cold remedies in addition to prescription drugs.
