Alexander Max Koester was a German painter. He depicted coastal landscapes and still lifes with flowers. After the artist first presented one of his landscapes with a family of ducks in Berlin in 1899, he earned the nickname "Duck Koester." The "duck" paintings were extremely popular with art lovers.
Rudolf Hausner was an Austrian painter, draughtsman, printmaker and sculptor. Hausner has been described as a "psychic realist" and "the first psychoanalytical painter".
A characteristic of his painting technique is the use of translucent ("glazing") resin oil paints in more than ten layers on top of each other over underpainting of acrylic paints, which gives the paint a special luminous depth. He also developed methods to create flawless transitions in pure oil painting without the use of an airbrush.
Carl Spitzweg was a German romanticist painter, especially of genre subjects. He is considered to be one of the most important artists of the Biedermeier era.
