Art Nouveau was a phenomenon with many faces. Between 1890 and 1910, artists developed a variety of styles from the plant-like forms of the Belgian-French Art Nouveau to the ornamentation of the Viennese Secession. They were all striving to create a new, modern style and pursued a comprehensive renewal of art and, in some countries, also a renewed national identity.

Art historian Uta Hasekamp edits and translates publications related to the history of art and writes, in particular, on older art and horticulture.
