On August 15, 2011 In Custodia Legis, the blog of the law librarians of the Library of Congress, published a post by John Hessler who works in the Geography and Map Division of this library. Recently Hessler had been doing research on land ownership in Roman law when rare book curator Meredith Shedd-Driskell showed him a notebook by Paul Krüger (1840-1926), one of the most important German scholars in the field of the study of Roman law in the nineteenth century. He published editions of the Codex Iustinianus, the Institutiones Iustiniani and with Theodor Mommsen the editio maior of the Digestae, editions still in use today. His edition of the Codex Theodosianus remained unfinished. This notebook turned out to be not the only item written by Krüger present in Washington, D.C. A whole wall contains the private library of Paul Krüger which was acquired by the Library of Congress in 1930. The post contains a link to the PDF version of an article in the Library of Congress’s Law Library Journal by Hessler on his findings. He promises another article in the Revue d’Histoire des Textes. My immediate reaction was this post from Washington does merit more attention.
When reading this really interesting post I somehow could not help asking myself whether Hessler and Shedd-Driskell were really the first to detect the notes of Paul Krüger? As it turned out to be I could get an answer to this question in an almost too quick way. In 2005 appeared Library of Congress Law Library: An Illustrated Guide (Washington, D.C.: Library of Congress, 2005) edited by Jolande E. Goldberg and Natalie Gawdiak. This book has been digitized by the firm with the seemingly unavoidable internet search website, and thus checking it is really easy. On page 72 of this book the collection is concisely described. The Library of Congress acquired Paul Krüger’s private library in 1930. The library consists not only of notes on his edition projects. There are also some manuscripts and manuscript fragments, transcriptions from manuscripts, manuscript collations, facsimiles of papyri, and much more. In 1934 the Library of Congress made a list of all the items which Goldberg and Nawdiak judged to be preliminary. It seems clear Hessler is the first to study materials in the Krüger collection since its acquisition and summary description.
Habent sua fata libelli! And the memory of scholars, even those as deservedly known among the scholars of Roman law, can have its fate, too. In the small but useful Historikerlexikon. Von der Antike bis zum 20. Jahrhundert, Rüdiger vom Bruch and Rainer A. Müller (eds.) (Munich 1991) the name of Paul Krüger is not mentioned. The articles in the volume Juristen. Ein biographes Lexikon. Von der Antike bis zum 20. Jahrhundert, edited by Michael Stolleis (Munich 1995) do not mention him either. Gerd Kleinheyer and Jan Schröder, the editors of Deutsche und Europäische Juristen aus neun Jahrhunderten (4th edition, Heidelberg 1996), do mention only Krüger’s praise for the edition by Johann Göschen of the Institutiones Gaii. In 1884 Paul Krüger and Wilhelm Studemund published an edition of this text. I did not find an article on Krüger in the main German biographical dictionaries, which you can search quickly at the German Biographie-Portal.
Of course editors have to make tough choices when selecting names for inclusion in a small or large biographical project. Just how tough is graphically shown by the rare appearances of Paul Krüger. At the Portal Rheinische Geschichte I did at last find an online article in German with more details on this scholar who teached at Marburg, Innsbruck, Königsberg and Bonn. The post at In Custodia Legis helps to bring Krüger back into light. I am sure further research in the materials at the Library of Congress will yield important fruits for the historiography of Roman law.
John Hessler has posted here some lecture notes and a number of photos from materials in the private library of Paul Krüger. The university library at Bonn has other papers from and adressed to Paul Krüger for which you can serach an online finding aid at the Kalliope portal.
