Since there were already Upjohn human pharmaceutical product listings that covered 1886 to 1956, Carol Orris and I decided that we would cover those products from 1957 to the end of The Upjohn Company in 1995. That meant the entire human pharmaceutical product history of the company would be available.

How did we do this? Because we are both long retired, we don't have access to any Pfizer in-house historical document collections or databases. We relied primarily upon old Upjohn product catalogs and price lists used by the sales forces. Each one has a complete list of human healthcare products. These publications are relatively common and we already had a collection of them from different years. Local public libraries had copies from other years so we were confident we had a good backbone of Upjohn product information. We also looked in annual reports and issues of The Intercom.

We started building our human pharmaceutical product listing in spreadsheet format at the end of December 2024 and by mid-February we had enough to post the 1957-1995 listing on this website. It's not finished. We still have to get specific dates for every product in the listing. We haven't tried to cover veterinary or other types of Upjohn products. Those projects may or may not come later.
