John Reid Wolfskill (September 16, 1804 – May 27, 1897) was a Mexican-American, California pioneer who helped establish development of California's agricultural industry in the Sacramento Valley in the 19th century. In 1842, Wolfskill was the first settler to plant vineyards and fruit trees there.[1] Born in the Bluegrass region of Kentucky, he migrated to join his brother William in California, where they bought land near Sacramento. Wolfskill became a pioneer of Solano County: "he was the first English speaking man to settle in the area around what is now Winters, California".[2]
His brother, William Wolfskill, had migrated earlier to California and also contributed to its agricultural development, primarily in Southern California in the area of present-day Los Angeles. After they were settled, their younger brothers Milton, Mathus, and Sarchal Wolfskill joined John on his land grant Rancho de los Putos, later renamed as the Wolfskill Ranch. In 1935 Wolfskill's descendants donated 100 acres of the ranch to University of California, Davis for use as an experimental orchard.
