Our History

AmerisourceBergen was built on a legacy of more than 100 years of excellence in pharmaceutical sourcing and wholesale distribution. Today, we impact millions of lives by applying innovation toward everything from the way pharmaceuticals are accessed to the delivery of personalized patient care.

The beginnings of something big

In 1871, Lucien Napoleon Brunswig becomes an apprentice to a U.S. druggist. This begins his journey to becoming a leader in the drug wholesale market. In 1882, Brunswig partners with Wheelock-Finlay, a well-established wholesale drug company. After Finlay’s passing, Brunswig takes on a partner, F. W. Braun in 1887. In 1907, Brunswig buys out Braun, renaming the business The Brunswig Drug Company. After relocating headquarters to Vernon, Calif., the company focuses exclusively on wholesale drug distribution.
