The sudden death of the young Baron von Sinclair, chargé d'affaires, forced W. C. Lotz temporarily into the rôle.

W. C. Lotz died in 1837 and Antonie moved the family to Pest (now one of the three constituent parts of Budapest; the one on the east bank of the River Danube).

Later he started on his own original works, first as a romantic landscape artist in scenes of the Alföld (the Hungarian lowland plain), and then as a creator of monumental murals and frescos in the style of the Venetian master Tiepolo.

In 1882 Lotz was appointed Professor at various art academies in Budapest, and in 1885 he became dean of a newly established department for women painters.

""Though born in Bad Homburg vor der Höhe, he belongs to Hungary by virtue of his Hungarian-born mother and his family's residence in this country.

Generously endowed in every other way, only luck and a commensurate material success have been denied him; he remains almost hidden, despite his rare genius."
