Joseph Mallord William Turner, was an English Romanticist landscape painter. Turner was perhaps the greatest landscapist of the 19th century. Although brought up in the academic traditions of the 18th century, he became a pioneer in the study of light, colour, and atmosphere. He is commonly known as “the painter of light” and his work is regarded as a Romantic preface to Impressionism. He anticipated the French Impressionists in breaking down conventional formulas of representation; but, unlike them, he believed that his works should always express significant historical, mythological, literary, or other narrative themes. A line of development can be traced from his early historical landscapes that form settings for important human subjects to his later concentration on the dramatic aspects of sea and sky. Even without figures, these late works are expressions of important subjects: the relationship of man to his environment, the power of nature as manifested in the terror of the storm or the beneficence of the sun. Unmatched in his time in the range of his development, Turner was also unrivaled in the breadth of his subject matter and the searching innovation of his stylistic treatment. Early in the 19th century, Turner was strongly criticized by conservative critics for his dynamic compositions and high-keyed colour. By the end of his life, although his Venetian subjects and more finished watercolours still appealed to some purchasers, his concern with atmospheric effects had developed along lines that departed from the trend in contemporary taste for realism and high finish, typified by the popularity of complex narrative painting. Turner’s growing reputation in the second half of the 19th century was in fact largely due to the championship of the influential English art critic John Ruskin, who published the first part of Modern Painters in 1843 to prove Turner’s superiority to all previous landscape painters and to extol his accurate rendering of natural appearance. In the 20th century a new appreciation of the abstract qualities of Turner’s late colour compositions strengthened his status as one of the most innovative and technically gifted painters of his century
