Dominique Lang (1874-1919) was born in 1874 (the year of the first Impressionist exhibition in Paris) and is considered today to be Luxembourg's most important Impressionist painter.

Lang adopted Impressionism from 1906 onwards, moving away from his earlier work in Symbolist and Pre-Raphaelite modes. The bold colours and vivid brushstrokes of Le Barrage, 1913, place Lang firmly in the tradition of Monet, Pissarro and Renoir. Largely unrecognised in his lifetime, Lang was unable to earn a reliable income from selling his work and he worked as art teacher to support his family.
