Here he married Anna Dumbser, daughter of the proprietor of the Inselwirt on the island of Frauenchiemsee, and made a temporary home.

The cessation of landscape classes at the Munich Art Academy obliged him to take lessons for a short time from Joseph Anton Sedlmayr [de] (1797–1863), and later from Carl Friedrich Heinzmann (1795–1846).

His work was shown to the public for the first time in 1833 at the Munich Art Society, and in 1843 he had his first exhibition in Prague.

The professor of historical painting Christian Ruben, who was married to Anna Dumbser's sister, was the rector of the Prague Academy.

Ruben obtained for Haushofer a position as professor of landscape painting which he held from 1845 to 1866.
