Hermenegildo Sosa is a Mexican painter and art professor who is best known for colorful depictions of Mexican rural landscapes, especially those of his home state of Tlaxcala. He was born there into a farming family, whose economic condition delayed his education as he had to work from a young age. In his teens he arrived to Mexico City to work as a domestic, but this allowed him to attend school, including painting classes. Eventually, he entered the Escuela Nacional de Pintura, Escultura y Grabado "La Esmeralda", where he eventually gained a career as a professor.
Sosa's has been extensively exhibited in the Mexico City area, his home state of Tlaxcala and has been exhibited in the United States and Germany. His work has been recognized with various awards, publications, tributes and membership in the Salón de la Plástica Mexicana.
