This collection contains the papers of four generations of the Read family of Philadelphia, consisting of John Read, Judge John Meredith Read, General John Meredith Read, and Harmon Pumpelly Read. The materials date from 1736 to 1896, with the bulk dating from 1792 to 1896, and include extensive correspondence, bills and receipts, genealogical notes, legal documents, newspaper clippings, photographs, scrapbooks and ephemera. The majority of the collection consists of General John Meredith Read's papers relating to his family history and genealogy, correspondence, and political materials. The collection is particularly valuable in illustrating Philadelphia social life, global and local politics, as well as Civil War experiences, as it includes extensive correspondence describing first-hand accounts of war activities as well as with several key political figures during the Civil War era.
