Lotty Rosenfeld (Carlota Eugenia Rosenfeld Villarreal) was a Chilean visual artist born in Santiago in 1943 and is known primarily for her work in printmaking, video art, and socially engaged art practice. She studied at the Escuela de Artes Aplicadas at Universidad de Chile, from 1967 to 1969. In 1979, Rosenfeld founded the artists' collective CADA (Colectivo de Acciones de Arte) with the poet Raúl Zurita, the sociologist Fernando Balcells, the writer and artist Diamela Eltit, and the artist Juan Castillo. Rosenfeld’s most iconic action is Una milla de cruces sobre el pavimento (A thousand crosses on the pavement, 1979), in which she attempted to reclaim public spaces that had been seized under the regime of Augusto Pinochet by placing tape across the dashed white lines separating traffic lanes on highways, turning the traffic markers into crosses or plus signs. Rosenfeld has been the recipient of the highest honors given in Chile: the Premio a la Trayectoria Artística (1995) of the Círculo de Críticos de Arte de Chile, the Paoa Prize (2001) of the International Film Festival in Viña del Mar, and the Premio Altazor de las Artes Nacionales (2003). Rosenfeld has exhibited at major museums including The Museum of Modern Art, New York; the Hammer Museum, Los Angeles; the Brooklyn Museum, New York; Museo de Arte Contemporáneo, Santiago; Museo Nacional Centro de Arte Reina Sofía, Madrid; and the Tate Modern, London. Her work was featured in the Chilean Pavilion at the 56th Venice Biennale (2015) and Documenta 12, Kassel (2007).
