Claude Monet
(1840 –1926)

Oscar-Claude Monet was a French painter and founder of Impressionism who is seen as a key precursor to modernism, especially in his attempts to paint nature as he perceived it. During his long career, he was the most consistent and prolific practitioner of Impressionism's philosophy of expressing one's perceptions of nature, especially as applied to plein air (outdoor) landscape painting. The term "Impressionism" is derived from the title of his painting Impression, Sunrise (Impression, soleil levant), which was exhibited in 1874 at the First Impressionist Exhibition, initiated by Monet and a number of like-minded artists as an alternative to the Salon.

Charles Sims
(1873 - 1928)

Charles Henry Sims RA RWS was a British figurative painter known for his portraits and landscapes. He initially became renowned as a leading Edwardian painter, but following the death of his son in World War I, his work became increasingly idiosyncratic, surreal and controversial. In 1920, he was appointed Keeper, or head, of the Royal Academy Schools, a post he was eventually forced to resign in 1926. At the same time, he became estranged from his wife and children. Sims' final paintings, the Spiritual Ideas, were to some viewers his "most beautiful works," but to others highly disturbing. He committed suicide in 1928.

Caspar David Friedrich
(1774 - 1840)

Caspar David Friedrich was a German Romantic landscape painter, generally considered the most important German artist of his generation, whose often symbolic, and anti-classical work, conveys a subjective, emotional response to the natural world. Friedrich's paintings often set contemplative human figures silhouetted against night skies, morning mists, barren trees or Gothic ruins. Art historian Christopher John Murray described their presence, in diminished perspective, amid expansive landscapes, as reducing the figures to a scale that directs "the viewer's gaze towards their metaphysical dimension".
