- Most of the Claude W. Unger collection at HSP once formed part of the extensive stock of Unger, a book and manuscript dealer in Pottsville, Pennsylvania, who was most active between 1925 and 1937. The collection contains letters and documents representing some 2,000 individuals connected to a wide range of subjects. People from the 19th century such as abolitionists, women’s suffragists, scientists, and politicians (particularly Pennsylvania politicians) are the most commonly represented individuals in the collection. In addition to the 40 document boxes, there are 112 volumes in the collection. The volumes consist of account books, court dockets, and school exercise books representing a variety of Pennsylvania Germans covering from the the late 18th to 19th centuries.
