Whilst staying in Venice, I paid a visit to the Peggy Guggenheim Museum. A big exhibition was devoted to Hans Arp, better known as Jean Arp, the dada artist and sculptor. You will have seen his distinct organically flowing sculptures. It was only in the very last section of the exhibition that an important factor of Jean Arp’s being, creativity and success emerged: His wife Sophie Taeuber.

I bet you have never heard of her. This is her story.
