After this the young doctor joined Karl von Hegel's, team working on the (ultimately) 27 volume compilation, "" ("The Chronicles of the German cities"), under the auspices of the "" (Historical Commission of the Bavarian Academy of Sciences). Von Weech applied himself to the second volume, working on the fifteenth century reports by Erhart Schürstab ("Kriegsbericht und Ordnung") concerning Nuremberg's war against Albrecht Achilles, Margrave of Brandenburg during 1449 and 1450. He also made other albeit lesser contributions to the compilation. After this he decided to switch from authorship to a university based academic career, and made plans to move to University of Tübingen, but in the end he moved instead to University of Freiburg, where he may have had his eye on a still unfilled teaching chair. He received his habilitation (higher academic qualification) from Freiburg in April 1862 for work "On the character and politics of Emperor Maximilian I".
