Doris Patty Rosenthal (July 10, 1889 – November 26, 1971) was an American painter, printmaker, designer, and educator, who made solitary explorations into remote areas of Mexico in search of indigenous peoples. Over several decades beginning in the 1930s, Rosenthal made hundreds of sketches in charcoal and pastel depicting the everyday life and domestic activities of Indian and mestizo peasant culture, which she later used to create large-scale studio paintings. LIFE magazine featured Rosenthal’s art and travels in Mexico in a five-page spread in 1943.
