Eva Hesse (1936-1970) is best known as an innovative sculptor working with unusual (and fragile, perishable) materials such as latex. This book focuses on the importance of her drawings, both as preparation for her sculptural work and as finished pieces in their own right. I love her line and find her work very moving, especially the drawings incorporating circles. I have an obsession with circles (Patrick Scott's work comes to mind - we have some of his tapestries in the University's art collection.)
This book was a gift from a dear friend and artist and is one I keep revisiting.
