Two exhibits in Berlin celebrate the late Italian designer Ettore Sotsass, whose red plastic Olivetti typewriter enlivened office spaces in the early 1970s. Ettore Sotsass at Galerie Ulrich Fielder displays some of Sotsass’s earlier commissions, including furniture for the Villa Astrua-Grassotti in Turin, and runs through June 23. Hans-Peter Jochum’s Olivetti Connection, which runs through June 9, features pieces that Sotsass and contemporaries Marco Zanuso, Enzo Mari, and Ugo Sissa (his minimalist 1940 sofa is shown) designed for Camillo Olivetti’s renowned Italian design firm. The exhibits document Sotsass’s career before his better known work with the Memphis Group, a progressive group of designers who embraced Postmodernism in the 1980s. • ulrichfiedler.com; www.hpjochum.de
