In 1865 he was appointed professor at the Maximilians Gymnasium and received the Great Golden Medal from
Maximilian II of Bavaria, for his chronological studies of the zodiac circle of Dendera and Manetho.[1]
From this recognition he was able to gain access to the
collections at the court and
library of king Ludwig I of Bavaria and study the royal collection of Egyptian artifacts held within. He later studied similar collections in Vienna,
Trieste, Rome, Florence, Paris, London and
Leiden (focusing especially on the
papyri). He made major contributions to the newly founded Journal of Egyptian Language and Antiquities. In 1869 he was appointed Honorary Professor of Egyptology, at
Munich University and
curator of the Egyptian collections.[2][3]
Some time later he began to be heavily criticized for the style of his writings[why?]. In the winter of 1872/73 he toured Egypt (Cairo, Alexandria and
Luxor) which led to him publish some Travel letters, about his experiences there. Subsequent research by others increasingly diminished the importance of his writings. After his resignation in 1882, he was gradually forgotten.[4][5][6]
