Henri Eugène Augustin Le Sidaner who was a contemporary of the Post-impressionists, was an intimist painter known for his paintings of domestic interiors and quiet street scenes. His style contained elements of impressionism with the influences of Édouard Manet, Monet and of the Pointillists discernible in his work. Le Sidaner favoured a subdued use of colour, preferring nuanced greys and opals applied with uneven, dappled brushstrokes to create atmosphere and mysticism. A skilled nocturne painter, he travelled widely throughout France and Europe before settling at Gerberoy in the Picardy countryside from where he painted for over thirty years.
