How can you date your historic Upjohn product? There are some resources to achieve that.

  • The company name changed in November 1902 from "The Upjohn Pill and Granule Company" to "The Upjohn Company".

  • There were 7 logos over the company lifetime 1886, 1894, 1907, 1913, 1938, 1945 and 1961. There is a page showing them on the web site.

  • There is a list of all products from 1886 to 1950, with the years that they were sold.

  • The Fluids Production log books from 1923 to 1939 still exist. They show individual batch numbers.

  • One tablet/pill manufacturing log book from the 1910s has survived. For tablet/pill manufacturing batch numbers:

    On 5 Dec 1911 batch # was 19282
    On 7 Dec 1915 batch # was 26698
    On 14 Nov 1916 batch # was 28550

    So 7416 batches were manufactured in 4 years, which is 1854 batches per year. Assuming this number has remained about the same each year then the numbering of tablet/pill batches may have started around 1901.

  • July 1st, 1963 was when zip codes were introduced and used on company labels.


Here is an example of how I can occasionally date a bottle back to the day it was filled (see photos below).

  • I bought this bottle of Excema Lotion on eBay.

  • The batch number on the label is 60379.

  • The production log book for January 3, 1925, shows that this batch was filled in that day.
