To mark what would have been Alf Lechner's 100th birthday, the Lechner Museum is celebrating one of Germany’s most important steel sculptors with a comprehensive centennial project comprising two exhibitions and an accompanying catalogue. The retrospective Alf Lechner 100: Materie Stahl features pieces from throughout all the phases of his creative work and traces how Lechner’s understanding of materiality changed—from the subordination of material to form, through to the recognition of steel as an independent player in the artistic process. A Matter of Perspective expands this view and positions Lechner’s work in the context of statements by international artists including Charlotte Posenenske, Robert Morris, Hanne Darboven, Richard Serra, Agnes Martin, Fred Sandback, Reiner Ruthenbeck, Nasreen Mohamedi, Franz Erhard Walther, and Riki Mijling. With images of sculptures along with academic texts, this volume opens up new perspectives on material aesthetics, ecology, and production. Text in English and German.
