Kandinsky and Munter were the moving spirits of the Blue Rider school, which pioneered the epochal turn from figurative painting to abstraction. This volume traces the development of the couple's personal and artistic relationship from its beginnings in 1902 to the key moment in 1914 when Kandinsky fled Germany and returned to his native Russia. The story of their life together - and of the underlying tensions which eventually drove them apart - is told through the artists' letters, in diary extracts and memoirs, and in reproductions of their finest paintings and sketches.
