In 1808 Savigny was appointed full professor of Roman law at Landshut. He remained in this position for a year and a half. In 1810 he was appointed to the chair of Roman law at the new University of Berlin, chiefly at the insistence of Wilhelm von Humboldt. Here, in connection with the faculty of law, he created a "Spruch-Collegium", an extraordinary tribunal competent to deliver opinions on cases remitted to it by the ordinary courts; and he took an active part in its labours. This was the busiest time of his life. He was engaged in lecturing, in government of the university (of which he was the third rector), and as tutor to the crown prince in Roman, criminal and Prussian law. During his time in Berlin, Savigny befriended Barthold Georg Niebuhr and Karl Friedrich Eichhorn.
