French artist Camille Pissarro (1830 – 1903), known as the “Father of Impressionism,” saw a subject and its light source as inseparable. Pissarro’s work depicted both rural and urban French life, occasionally revealing his radical political beliefs. He mentored Paul Cézanne and Paul Gaugin when they were aspiring artists, and vastly contributed to Impressionist theory. Pissarro fought daunting criticism for most of his life, while trying to achieve validation for his revolutionary style. His works were eventually accepted, and now command millions of dollars.
