Alfred de Bréanski Sr. was a noted British landscape painter born to a family of artists. At the early age of 20 his first painting was accepted by the Royal Academy. Thereafter he exhibited regulary with the RA and the Royal Society of British Artists. De Bréanski's expertise was in painting remote Welsh and Scottish mountain scenes, particularly the Scottish lochs. His work fuses a Romantic sensibility and a great spiritual respect for nature with accurate realism, continuing the 19th century landscape tradition. Detail can be found in his grand scenes within the textures of natural elements and in the sparkling plays of light. Influences are said to have included John Constable and J.M.W. Turner, and even French Impressionist inspiration has been suggested in his use and range of colour.

In addition to the Royal Academy, de Bréanski also exhibited with the Royal Society of British Artists, New York Watercolor Society, Royal Cambrian Academy and the Royal Institute of Oil Painters.
