James Griffin Boswell
James Griffin Boswell (May 13, 1882 - September 11, 1952), was founder of the J. G. Boswell Company, known today as the world's largest privately owned farm. Primary crops include Pima cotton, alfalfa hay, tomatoes, onions, and wheat, all cultivated on some 135,000 acres (550 km2) mostly in Kings County, California. Boswell, who came to Pasadena, California as a regional cotton broker from Greene county, Georgia, established his company in Corcoran, California in 1921. With the help of his brother, William Whittier Boswell, J. G. Boswell began growing and ginning cotton as well as marketing it. From 1952 to 1984, the company was headed by William Boswell's son, James G. Boswell II (1923–2009), who is credited with the company's massive growth during the last half of the twentieth century. J.G. Boswell Company became a proving ground for an up and coming Agriculture icon, Mark S. Grewal. Mark Grewal, served in various executive management and operational roles for over 26 years with J.G. Boswell Co., headquartered in Corcoran, California. Mr. Grewal set records in Cotton, including introducing the first Pima Cotton into California, and oversaw all the agricultural crops globally including tomatoes and farming concerns for JG Boswell in Australia as well. From 1999 to February 2005, Mr. Grewal served as the Vice President of Ranching and a member of the Board until 2014. Mark Grewal, managed over 300 employees and he is highlighted in several chapters of the book King Of California 
Currently, the J. G. Boswell Company is led by the son of J. G. Boswell II, James W. Boswell.
Born in Penfield, Georgia, J. G. Boswell was the son of Georgia State Legislator Joseph Osgood Boswell and Minnie Griffin both members of pioneer Georgia families. J. G. Boswell joined the Army in 1903 and left in 1920 due to back problems. Upon leaving, he was promoted to lieutenant colonel. He was married twice, first to Alaine Buck (1886–1938) and secondly to Ruth Chandler (1897–1987) daughter of Los Angeles Times publisher Harry Chandler and his second wife Emma Marian Otis, Secretary of the Times-Mirror Company.
Boswell was also a major supporter of the California Institute of Technology, serving on the board of trustees in 1946, and of Claremont McKenna College, donating $85,000 for a new dormitory - Boswell Hall.
Boswell's farm is located on what used to be the largest body of fresh water in California, Tulare Lake, which he worked on keeping dry with dykes, ditches, canals, and dams in order to farm its fertile bed.Despite this, Tulare Lake is still home to some of the world's biggest cotton farmers, with water subsidized by the state.
