The artist Nell Walden (originally Nelly Roslund) was born in 1887 in Landskrona. After studying in Sweden, she went on inspirational journeys around Europe. In Berlin, she got to know the artist and composer Herwarth Walden, founder of the magazine "Der Sturm". The two fell in love and married in 1912, this was the starting point for Nell’s artistic career.
Herwarth Walden also founded an avant garde art gallery with the same name, “Der sturm”. The gallery focused on expressionist art and exhibited artists from all over Europe in Berlin in the 1910s and 20s. "Der Sturm" introduced artists such as Marc Chagall, Wassily Kandinsky, and Franz Marc and through the gallery, where Nell was a key figure, she came to know the most important European artists of the avant-garde.
