Julius Ralph Davidson or JR Davidson (February 7, 1889-May 2, 1977) was a Mid-century modern American architect known for advancing modern architecture in Los Angeles and participating in Arts & Architecture magazine's Case Study House Program.Davidson was part of a group of Jewish architects who sought refuge in Los Angeles after having to flee Europe due to persecution inflicted by the Nazis including the Holocaust. This group included Richard Neutra, Rudolph Schindler, Kem Weber, and Paul László who furthered modern architecture in Los Angeles in the 1930s and 40s. Architectural historians and critics have described Davidson as being conversant in and talented at bridging both Art Deco, International, and Modernist styles. His modern interiors have been noted for their warmth, fluidity, and well-planned storage space. Writer Thomas Mann, who had an aversion to glass-box styles, selected Davidson as the architect of his Pacific Palisades home for his moderate modernism.
