the unique style of who painted impression sunrise
Before the 1860s and the debut of Impression, Sunrise, the term “impressionism” was originally used to describe the effect of a natural scene on a painter, and the effect of a painting on the viewer. By the 1860s, “impression” was used by transference to describe a painting which relayed such an effect.  In turn, impression came to describe the movement as a whole.
Impression, Sunrise became the most famous in the series after being debuted in April 1874 in Paris at an exhibition by the group “Painters, Sculptors, Engravers etc. Inc.”  Among thirty participants, the exhibition was led by Monet, Edgar Degas, Camille Pissarro, Pierre-Auguste Renoir, and Alfred Sisley, and showed over two hundred works that were seen by about 4,000 people, including some rather unsympathetic critics.
