Post-Impressionism or Postimpressionism is the term coined by the British art critic Roger Fry in 1910 to describe the development of French art since/after Manet.
In connection with a Manet exhibition in 1910, Fry used the label to contextualise the works of the artist specifically as a catalysator.
The distinction between Impressionism and Postimpressionism can be insignificant at times. Postimpresionists continue the journey of the Impressionists, but have no dogmatic ideas of avoiding black for instance. Also they do not insist on everything to thought of as dabs of colour – even if it is the case. The concern is not great. They also begin to introduce elements that you would consider Expressionists. Distortion, application of certain colours that are not true to nature but express emotion. In that regard, the predominantly French Post-impressionism and fauvism, have much in common with German Expressionism.
