In 1809 he returned to Hamburg to become a pastor. But the city had a small fund to support one of its theologians as a lecturer at Heidelberg. This was wisely appropriated to Neander, who promised more as a scholar than as a preacher. Accordingly, in 1811, we find him established at Heidelberg as a teacher in the University, he having previously, on his public profession of Christianity, assumed the name of Neander deriving it from the Greek, [Greek: nheos haner], “a new man,” to signify the entire change which had come over him.
