The publication addresses a highly topical subject: the interaction between art, science, and social processes - the basic working principle of the two outstanding artists Helen Harrison (1927–2022) and Newton Harrison (1932–2022), who are seen as the founders of Eco Art. It examines the development of their ideas, processes and techniques in the field of ecological art and their influence on nature and society using the example of their Californian works from the last 50 years, which were a laboratory for a wealth of innovative artistic strategies. The Harrisons later used these strategies in other parts of the world to help solve current environmental problems in local and global contexts. The volume contains critical essays as well as a revealing interview with Newton Harrison, in which he reflects on the development of their Californian oeuvre, and numerous illustrations documenting many of the artworks for the first time.
