The celebrated Adolpho Leirner Collection of Brazilian Constructive Art consists of the finest examples of Geometric Abstraction in paintings, constructions, drawings, posters, and graphic materials by Brazil's foremost artists of the post-World War II era. Long regarded as a brilliant window into the seminal decades of modernization in Brazil, the collection was built by São Paulo-based collector Adolpho Leirner beginning in the 1960s and acquired by the MFAH from 2005 to 2007. Among the cutting-edge artists and groups represented are Lygia Clark, Hélio Oiticica, Alfredo Volpi, Grupo Ruptura, and Grupo Frente. The collection is a key chapter in the global story of Modernism and an important component of the Latin American art initiative at the MFAH.
