LONDON – Hilma af Klint (Swedish, 1862-1944) and Piet Mondrian (Dutch, 1872-1944) were two of the most imaginative artists of the 20th century. While they never met, they shared the same deep connection to the natural world and the desire to understand the forces behind life on earth. A major new exhibition at Tate Modern, Hilma af Klint and Piet Mondrian: Forms of Life, will put these two visionary painters in close dialog for the first time. The show will open on April 20 and close on September 3 and will feature around 250 works, including paintings, drawings and archival materials, revealing how their art reflected radical new ideas, theories and scientific discoveries in an era of rapid social change.
