Georges William Thornley : un postimpressionniste singulier

Exhibition at the MAHPP, Pontoise, 17 October 2026 – 17 January 2027,
then at the William Thornley Museum, Osny, February – June 2027

Although he enjoyed his moment of glory during his lifetime, Georges William Thornley (1857–1935) was soon forgotten, unlike his predecessors – notably Monet, Degas and Pissarro – whose almost universal fame has endured to this day. The work and career of the Post-Impressionist Thornley, however, deserve to be faithfully restored. A fiercely independent landscape painter and heir to the Barbizon school, through his watercolours and oil paintings he eventually returned to his youthful passion—travel—from which he drew the ceaselessly renewed inspiration of a man constantly transcended by nature.

Several analytical approaches enable us to better understand the complex personality of a man who often deliberately chose to shun social conventions. He first distinguished himself as one of the greatest lithographers of his time – a decisive step in establishing his reputation – which helps us to understand the subtle artistic connection that would lead to a close and privileged relationship with Claude Monet, Camille Pissarro and Edgar Degas.

This book, published to mark the exhibition dedicated to Thornley, consists of a monograph followed by a catalogue raisonné. It is intended as a tribute to this artist, who has been unjustly overlooked by history.
