Heine had known and admired Karl Wilhelm Feuerbach, the mathematician, since his student years. After Karl's death Heine was good friends with the elder brother Joseph Anselm Feuerbach, who taught archeology in Freiburg. Joseph Heine soon recognized the artistic talent of his friend's son Anselm Feuerbach and tried to encourage and support him. His and von Zwehl's attempt to send the young painter to Wilhelm von Kaulbach in Munich was a failure: in 1850 Feuerbach went to Antwerp instead.
