The cornerstone of the Museum’s Constructive art holdings is the Adolpho Leirner Collection of Brazilian Constructive Art, acquired between 2005 and 2007. This world-renowned collection consists of nearly 100 extraordinary examples by Concrete and Neo-Concrete groups that flourished in São Paulo and Rio de Janeiro between the 1950s and 1960s. Featured prominently in the Leirner Collection is the innovative production by the leaders of these two groups—Lygia Clark, Waldemar Cordeiro, and Hélio Oiticica—as well as works by independent artists such as Milton Dacosta, Mira Schendel, and Alfredo Volpi. The Leirner Collection is featured on Google Arts & Culture. Explore resources from The Adolpho Leirner Collection, Library, and Archive here.
