Johann Adam Andreas of Liechtenstein

Johann Adam Andreas (1657-1712) was the second Prince of Liechtenstein.

In 1699 he acquired the domain of Schellenberg, and in 1712 the county of Vaduz. These two domains would later form the present principality of Liechtenstein.

Johann never took up an office at the Imperial court but did case by case work. He was a financial expert and thus tended to aid in these areas. He was known informally as Hans Adam the rich.

Besides managing his property, he also took great interest in art. He bought works of Rubens and van Dyck for his collections. He was one of the most generous patrons of his time. Johann set himself two memorials, a Palace in Bankgasse street in Vienna and a summer palace in Rossau.
