Gerardo Murillo Coronado, known as Dr. Atl (1875–1964), was a Mexican painter, writer, and intellectual. Born in Guadalajara, he trained at the National School of Fine Arts in Mexico City in the 1890s. Alongside Diego Rivera and David Alfaro Siqueiros, he contributed to the development of muralism in the early 20th century. His work focused on Mexico’s volcanic and mountainous landscapes, often painted en plein air with a romanticized approach.
Dr. Atl’s paintings feature dynamic geological formations, particularly volcanoes, rendered in bold, expressive strokes. His palette relied on earth tones and atmospheric effects, blending post-impressionist techniques with a nationalist perspective. He frequently used "aeropittura", aerial perspectives, to depict Mexico’s terrain. Beyond painting, he documented volcanic activity, producing thousands of studies of Paricutín’s eruption in the 1940s, later published in illustrated volumes.
As a theorist and educator, Dr. Atl promoted the integration of indigenous Mexican culture into modern art, shaping the ideological framework of muralism. His writings on art, politics, and vulcanology expanded his influence. Though his later work diverged from dominant Mexican modernist styles, his focus on landscape as a symbol of national identity influenced subsequent artists.
