Statement of Significance (as of designation - November 11, 1971):
From 1942 until 1966, this was the principal home of Upton Sinclair (1878-1968), one of the most influential American novelists in the area of social justice. Sinclair became famous after his investigation of the meat packing industry resulted in his publication of the expose "The Jungle" in 1905. His novel resulted in an investigation of the industry and reform of the Pure Foods and Drugs and Meat Packing acts in 1906. "Dragons' Teeth," published in 1942, on the rise of National Socialism won him the Pulitzer Prize. Virtually all of Sinclair's later works were written here in this neo-Mediterranean house.
