After attending the Ortwein school in Graz in 1999, Christian Eisenberger studied Transmediale Kunst in the class of Brigitte Kowanz at the Academy of Fine Arts Vienna from 2000 to 2004.
In 2013 he participated in the artist in residence programme of one world foundation (in cooperation with Galerie Krinzinger) in Sri Lanka.
Christian Eisenberger initially became known for thousands of painted cardboard cutouts[2] which he, at first anonymously, placed in public space.
Eisenberger's art also contains numerous references to classical genres, such as expressionist painting and sculpture.
The themes around which his work revolves are equally diverse, as he treats classical subjects of art history (life, death, vanitas motives) as well as political topics, such as criticism of institutions.
