Shirley Rabé Masinter grew up in New Orleans and has made the city her main subject. She got her start in advertising, working downtown through the 1950s, ‘60s, and ‘70s before pivoting to fine art. Returning to school to study painting, she’d bike from her house in the Carrollton neighborhood to the Tulane campus for classes while at the same time continuing part-time work and raising a family. She has worked as a painter since the late 1980s and is now working in her 89th year. She met me at LeMieux, where her last show, “Louisiana Now,” was exhibited, to talk about her process.
