Revolutionary French Post-Impressionist painter Paul Cezanne’s rebellion against 19th century Impressionist conventions sparked the radical new world of 20th century modern art. Although he was ridiculed by critics at the time, both Picasso, Matisse, and many others cite him as an influence and accolades came post-humously. His experimentation with optical perception, geometric simplification and fractured forms, kept his style changing significantly over his lifetime. An eccentric genius, Cezanne was a solitary enigma to those who knew him best, including his own family.
