Parke, Davis & Company was America's oldest and largest drug maker that played an important role in medical history. It was founded in Detroit, Michigan, by Dr. Samuel P. Duffield, a physician, and pharmacist. Dr. Duffield and Hervey Coke Parke formed a partnership in 1866, with George S. Davis becoming a third partner in 1867. Dr. Duffield withdrew in 1869 because of poor health and an interest in practicing medicine. The partnership adopted the name Parke, Davis, or Parke-Davis in 1871 and was incorporated as Parke, Davis & Company in 1875. The company is credited with building the first modern pharmaceutical laboratory and developing the first systematic methods of performing clinical trials of new medications. In 1970, Parke-Davis was acquired by Warner-Lambert. It is now a subsidiary of Pfizer, which acquired Warner-Lambert in 2000. The Parke-Davis Research Laboratory is a National Historic Landmark and, the surrounding Parke-Davis and Company Pharmaceutical Company Plant is on the National Register of Historic Places.
