Anderson, Clayton & Co.. In 1904, Frank E. Anderson, his brother, Monroe D. Anderson, and his wife's brothers, William L. and Benjamin B. Clayton, formed the partnership of Anderson, Clayton & Co. in Oklahoma City. The successful cotton firm moved its headquarters in 1916 to Houston and built Long Reach, a cotton compressing-storing-shipping complex covering 32 acres on the new Houston Ship Channel, including a wharf for the simultaneous loading of eight steamships. At the time, the world's cotton-trading center was the New York Cotton Exchange; Houston and other cities had lesser exchanges. In 1924, the Houston Cotton Exchange moved into a new building at this site. Anderson, Clayton & Co. became the building's principal tenant for many years. From the eleventh floor headquarters, company officials supervised more than 24,000 employees stationed around the world. The company incorporated in 1945. By 1960, coffee had surpassed cotton in sales, and the firm continued to diversify, with interests in related foods and textiles. By the 1980s, the food division had become its principal asset, and the Quaker Oats Company acquired the business in 1986. The firm's Houston partners greatly influenced the city's development and enriched its future. The M.D. Anderson Foundation established the Texas Medical Center, the University of Texas-M.D. Anderson Cancer Center and many other projects. Ben Clayton created the Clayton Research Foundation and other philanthropies. Will Clayton became prominent as Undersecretary of State for Economic Affairs and for his work on the Marshall Plan after World War II. He and his wife gave their home to Houston's Public Library. In 1996, the former Cotton Exchange Building became the Anderson Clayton Courthouse Annex. (2005) #13043

Micham Main. Little is known about this Anderson County pioneer until he married Elizabeth Van Winkle in Crawford County, Illinois, in 1820. The Mains lived in the Illinois township of Palestine until 1833, when, drawn by a favorable change in the Mexican colonization laws, they moved their family to the Nacogdoches District of what is now Texas. Micham Main applied for a land grant in David G. Burnet's colony and received property in what is now Anderson County in 1835. He farmed the land, as was required under the terms of his grant, and joined the Republic of Texas army for a brief tenure in 1836. Ten years later, the first Texas legislature created Anderson County, and Micham Main was appointed as one of three men to establish a site for a county seat and to give it a name. Along with James Box and John Parker, also from Illinois' Palestine township, a 100-acre tract of land was selected and accepted by the Anderson County commissioners court. Early histories of Anderson County credit Micham Main with naming the new Anderson County seat Palestine for his former residence in Illinois. Later accounts, however, recognize John Parker for this action. Primary source materials that could verify either claim have not surfaced. Nevertheless, Micham Main remains an important part of Anderson County's early history. He died at his home in 1847 and is buried in the Swanson Cemetery. (2002) #12630
