Money poured into LACMA during the boom years of the 1980s, a reportedly $209 million in private donations during director Earl Powell's tenure. To house its growing collections of modern and contemporary art and to provide more space for exhibitions, the museum hired the architectural firm of Hardy Holzman Pfeiffer Associates to design its $35.3-million, 115,000-square-foot Robert O. Anderson Building for 20th-century art, which opened in 1986 (renamed the Art of the Americas Building in 2007). In the far-reaching expansion, museum-goers henceforth entered through the new partially roofed central court, nearly an acre of space bounded by the museum's four buildings.
