Moore (1882-1974) was a landscape and animal-portrait painter, and etcher, was born in Washington DC and lived there for seventy years. He became a noted painter of scenes of nature, and his style early in his career showed the Barbizon School influence but later became more Impressionist and less Tonalist. His snow scenes were especially popular. Benson studied at the Linthicum Institute and at the Corcoran School of Art with Edmund Messer, Richard Brooke and Max Weyl, teachers who were part of the late-nineteenth century landscape school. In 1902, he began work with the Maurice Joyce Photo-Engraving Company in Washington D.C., and there he worked with Dr. Alexander Graham Bell by making drawings to develop hearing aids for the deaf. He also did drawings for Dr. Emile Berliner, inventor of the graphophone, and for the Smithsonian. He taught etching both privately and in the art school of the sculptor Clara Hill. With Charles Seaton, Winfield Clime and Edwin Cassedy, he became a founding member of an informal group of Washington painters who called themselves "The Ramblers Sketch Club." Together with others, many of them "Sunday painters," they roamed the surrounding countryside, painted and then critiqued each other's work. In 1920, the group evolved into the respected Washington Landscape Club that included many big-name art figures and with whom Moore often exhibited. He belonged to more than forty arts organizations and was a founding member of The Miniature Painters, Sculptors and Gravers Society of Washington D.C., which held its inaugural exhibition in 1931 at the Corcoran. He had many one-man shows, a highlight being in 1928 at the Corcoran Gallery with his etchings, drypoints, and lithographs.
