International Association of Machinists (IAM) dues book, circa 1916, belonging to J.R. Fisher, provides documentation of his membership in Lodge 687, Philadelphia, Pennsylvania. Fisher, identified as a lathe worker, is recorded as card number 288601. The cover exhibits wear commensurate with age, including discoloration and rubbing. The inscription "J. Rez" is faintly visible on the cover, potentially an abbreviation or nickname. The interior contains over 36 canceled red/pink dues stamps, dating from March 1915 to January 1918, documenting Fisher’s dues payments. A "Transfer Account" stamp dated March 1, 1915, indicates prior membership in another IAM lodge. Signatures from Lodge President Joseph Powers and Financial Secretary Edw. B. Hirst are present. The book's internal structure provides insight into the IAM's administrative practices. Sections include spaces for "Lodge and Transfers on Other Side," "Ledger Page," "Identification," (with fields for physical description and address), "Benefits," "Grand Lodge Assessments," "Unemployed and Strike Stamps," "Local or District Lodge Assessments," and "Referendum." Some sections contain handwritten entries, while others remain blank. The pages are yellowed, and the binding displays fraying along the spine; however, the text remains legible. The book offers information regarding the financial and organizational activities of the IAM during the early 20th century. It provides a record of a working-class individual's involvement with the labor movement, specifically within the context of Philadelphia during the World War I era. This item may be of interest to researchers studying labor history, the IAM, or genealogical research pertaining to the Fisher family.
