Mortimer Jerome Adler was an American philosopher, educator, and popular author. As a philosopher he worked within the Aristotelian and Thomistic traditions.

Paul Cézanne was a French artist and Post-Impressionist painter whose work laid the foundations of the transition from the 19th-century conception of artistic endeavor to a new and radically different world of art in the 20th century. Cézanne's often repetitive, exploratory brushstrokes are highly characteristic and clearly recognizable. He used planes of colour and small brushstrokes that build up to form complex fields. The paintings convey Cézanne's intense study of his subjects.
Pablo Picasso was a Spanish painter, sculptor, printmaker, ceramicist, stage designer, poet and playwright who spent most of his adult life in France. Regarded as one of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon , and Guernica , a dramatic portrayal of the bombing of Guernica by the German and Italian airforces.
