Herwarth Walden (actual name Georg Lewin; 16 September 1879 – 31 October 1941) was a German expressionist artist and art expert in many disciplines.

He is broadly acknowledged as one of the most important discoverers and promoters of German avant-garde art in the early twentieth century (Expressionism, Futurism, Dadaism, Magic realism).

[1] He discovered, sponsored and promoted many young, still unknown artists of different styles and trends, such as the Blaue Reiter and Italian Futurism.

[2] He also discovered and promoted several poets, notably August Stramm, Otto Nebel, and Franz Richard Behrens.

From 1901 to 1911, Walden was married to Else Lasker-Schüler, the leading female representative of German expressionist poetry.
