Here is a description of the lecture and the donation Roetzel made to the Pitts Theology Library of his personal correspondence with Käsemann:
"Professor Roetzel was one of several prominent American scholars who worked with Professor Käsemann in Tübingen and brought his influence into North American scholarship. Prof. Roetzel is donating to the Pitts Theology Library his personal correspondence with Prof. Käsemann, a collection of letters that ranges in topics from personal details related to his visit in Tübingen to substantive conversations about Pauline theology. The Pitts Theology Library is using Prof. Roetzel’s donation as the beginning of a curation effort of other American scholars who own Käsemann correspondence. Building upon existing archival items, Pitts has contacted several New Testament scholars who have indicated they are interested in participating in this endeavor. Professor Roetzel’s lecture will provide the context to this collection and celebrate the enormous contributions of Professor Käsemann."
