Between 1880 and the outbreak of war in Europe in 1914, many hundred artists must have either been trained in Paris academies, or developed their own impressionist style. You will find their paintings in their national and regional galleries, in most of the countries around the world.
Sadly very few of them are accessible in books and the Internet. Where they are, there is usually too little information to support coverage in this series. However a few stand out, and there are one or two good images of their work available. I therefore offer the following short selection of those, to illustrate how broad was the influence of Impressionism.
I apologise if your favourite painter or nation is not represented: if you do know of anyone who painted in impressionist style before 1914, and for whom there are at least 5 good quality images available without copyright problems, please contact me and I will be only too happy to try to post an additional article for this series.
The next article in this series will consider what makes a painting Impressionist, before I try to pull together information from the previous articles and make some sense out of it.

Born in Azul, he went to Buenos Aires in 1879, where he was trained by local artists. In 1887 he became artist-in-residence on a ranch in Córdoba Province, where he developed his landscape technique. Growing success enabled him to travel to Paris in 1895. He returned to Buenos Aires in 1901, and popularised Impressionism. He was Dean of the School of Art of the University of La Plata, and a leading post-Impressionist.
Roderic O’Conor (1860-1940) Ireland

Born in County Roscommon, Ireland, he attended the Royal Hibernian Academy, then went to Antwerp. He went on to Paris, and in 1892 lived and painted in the artists’ colony at Pont-Aven in Brittany. He befriended Paul Gauguin, but most frequently painted using textured strokes of contrasting colour, more like the style of Vincent van Gogh.
Nadežda Petrović (1873-1915) Serbia

Born in Čačak, she moved to Belgrade where she started her artistic training. She studied in Munich, and in the first decade of the twentieth century her paintings were widely exhibited in Europe.

She died of typhus during the latter war.

He went to Paris in 1889, where he acquired his Impressionist style. In 1894 he slashed one of his own paintings on the final day of its exhibition. In his later years he became more of a Symbolist, but he died young of tuberculosis.
