As a painter, Walter Pach followed the dominant European trends of his day. His early style echoed Impressionism, but evolved, after studying Italian Renaissance painting, into more simplified images with heightened color palettes. He embraced Cubism and Fauvism in works such as Storm on the River (1914), which depicts a stylized, vibrant landscape featuring geometric, interlocking planes. Even upon reverting to a figurative style after 1920, his portraits, landscapes, and still lifes retained a quintessentially modern elements, evoking Paul Cézanne and Vincent van Gogh, whom he admired. Despite his artistic achievements, Pach is best remembered as an influential art historian and critic who championed Europe’s emerging modernist viewpoint to the American public. He also played a key role in founding the Armory Show.
