In 1965 Gerhardsson became professor in New Testament exegesis at Lund University; a position he held to his retirement in 1992. However, he continued to be very active in the research seminar for many years to come. Thus, I had the occasion to learn to know Gerhardsson as a scholar and friend during my own studies at Lund University in 2003-2006. I remember his encouragement and advice, and the several personal letters he used to write on various occasions, e.g., when I had presented him a copy of my dissertation.
In relation to my own special area, textual criticism, and my extensive collations of Greek MSS, I particularly remember him sharing about his own ordeal as doctoral student, when Prof, Harald Riesenfeld assigned him to collate and study a lectionary MS in Uppsala (Uppsala Gr. 4 = Gr.-Al. L1256). "In order to study Greek MSS, you need a lot of 'sittfläsk' ['butt flesh']." Gerhardsson's patient collation work and "sittfläsk" resulted in the article, “Ein griechisches Lektionar,” Svensk Exegetisk Årsbok 24 (1959): 72-88. Incidentally, Riesenfeld and Gerhardsson have both been presidents of Studiorum Novi Testamenti Societas (SNTS) in 1968 and 1990, respectively.
In Gerhardsson's 1992 farewell lecture (available in Swedish here) he gives a retrospective view of his research, listing his favorite subjects: tradition and transmission, the role played by Israel's confession of faith (the Shema) for Jesus and Early Christianity, New Testament Ethics, and the Gospel of Matthew. These areas are reflected in Gerhardsson's many publications (see selected bibliography below), but of course Gerhardsson is most well-known for his work in the first area.
In a 2009 tribute to Gerhardsson, Jesus in Memory: Traditions in Oral and Scribal Perspectives (ed. S. Byrskog and W. Kelber; Waco: Baylor, 2009) — a volume of essays which gives an excellent overview and evaluation of Gerhardsson's groundbreaking research — his student and successor at Lund University, Prof. Samuel Byrskog writes in the introductory chapter (p. 4):
Few scholars have influenced New Testament scholarship in the areas of orality, memory, and tradition more profoundly than Birger Gerhardsson. Today, as these topics have again become important in biblical scholarship, his pioneering work takes on a new light. . . . The discussion of his ideas, even when there is disagreement, is a manifestation of the crucial importance of his work.
Gerhardsson will be missed not only by his family, but by many colleagues and friends in Sweden and all over the world.
In this bibliography I list some of Gerhardsson's studies, primarily as they are now available in reprints and translations.

This is a reprint of the revised edition of Gerhardsson's thesis (1961), augmented with the follow-up booklet Tradition and Transmission in Early Christianity (1964), and a signficant foreword by Jacob Neusner (who refers to it as "an act of penance" since Neusner had reviewed Gerhardsson's original study three decades earlier "in an uncomprehending and unappreciative, indeed dismissive way.").
