Another underrated flemish master of the 19 th century. It was impossible to find better resolution photos on the internet, these are the best I could find. Such a shame that there is so few interest in keeping alive the memory of these amazing painters. Koster studied under BJ van Hove at the Royal Academy of Art in The Hague. Later he studied at the Städel in Frankfurt am Main. After his studies he worked in Amsterdam, where he joined in 1852 the Royal Academy. Between 1858 and 1879 he was director of the Pavilion in Haarlem. He then worked in The Hague and Dordrecht, where he died in 1892.
"For over 90 years, there has been a concerted and relentless effort to disparage, denigrate and obliterate the reputations, names, and brilliance of the academic artistic masters of the late 19th Century. Fueled by a cooperative press, the ruling powers have held the global art establishment in an iron grip. Equally, there was a successful effort to remove from our institutions of higher learning all the methods, techniques and knowledge of how to train skilled artists. Five centuries of critical data was nearly thrown into the trash. It is incredible how close Modernist theory, backed by an enormous network of powerful and influential art dealers, came to acquiring complete control over thousands of museums, university art departments and journalistic art criticism" http://www.artrenewal.org/articles/Philosophy/ArtScam/artscam.php
