Paintings, drawings, photographs, moving pictures, poetry, and letters infuse this episode of Word By Word: Conversations With Writers. This is because host Gil Mansergh’s and studio engineer Anthony Garcia’s guest is the respected biographer Carolyn Burke with her latest book Foursome. The four people who burst forth in this volume are photographer Alfred Stieglitz, painter Georgia O’Keefe, movie maker Paul Strand, and writer/painter Rebecca Salsbury.
