Alexander Calder, Ellsworth Kelly, and Sol LeWitt are the three artists whose work Doris and Donald Fisher collected in the greatest depth. The installation features approximately two dozen works by each artist, exploring their artistic breakthroughs across a spectrum of important works. Although their work emerged in distinct historical contexts, they are united by their engagement with architecture, their embrace of different strategies of seriality, and their commitment to opening the autonomous art object to elements of chance or rule-based systems. The floor also features Co-Lab, a newly created studio space programmed for hands-on activities that support learning and making for adults, families, and children.
