Alfred Jensen

Born in Guatemala, Alfred Julio Jensen was an abstract painter. His paintings are often characterized by grids of brightly colored triangles, circles or squares, painted in thick impasto. Conveying a complex web of ideas, often incorporating calligraphy or numerical systems, they are frequently referred to as "concrete" abstract art.[2] After his death in 1981, the Guggenheim organized a major retrospective of his work, having held his solo exhibition there in 1961.
