Pele deLappe: RIP
Life long social realist painter, printmaker and activist, Pele deLappe (pronounced: “Peelee Dahlap”), died from a stroke on Monday, October 1st, 2007, at the age of 91. Ms. deLappe’s art captured the life and times of her native San Francisco during the depression years and beyond, but the universal humanistic themes addressed in her artworks also gave them an eternal quality. She remained active and productive as an artist until the very end. …
Already sketching the people of her city as a precocious 14 year old, deLappe met Frida Kahlo and Diego Rivera when the famed Mexican artists visited San Francisco in 1930. Rivera had been commissioned to paint murals for the San Francisco Stock Exchange and the California School of Fine Art (now the San Francisco Art Institute). Undoubtedly inspired by the couple and the experience of making drawings with Kahlo, deLappe traveled to New York to attend art school. When she returned to San Francisco in 1934 at the age of 18, she threw herself into the city’s maritime strike, contributing drawings and cartoons to the newspapers of striking workers, getting arrested twice while supporting the work stoppage, and making a series of portrait paintings depicting rank-and-file union members. It would be the beginning of a lifelong commitment to creating social engaged works of art.
