Walter Henry Cousins, pharmacist, poet, and historian, the son of Henry Clay and Frances Cousins, was born on August 18, 1878, near Whitson, Texas. He attended Whitson, Walker, and Haunted Hill schools. In 1898 his family moved west to Haskell County, where Walter worked as a bronco buster on the MN Ranch in Haskell, Throckmorton, and Knox counties. He was also camp cook for trail drives across Oklahoma during this period. In 1902, after an apprenticeship, he became a licensed druggist. That year he also married Sue Reeves McClendon. They eventually had two children. Cousins was appointed a member of the State Board of Pharmacy in 1913 and became secretary in 1920. He held this office until December 1, 1941, when ill health forced him to retire. He bought and became editor of the Southern Pharmaceutical Journal in Dallas in 1915. That year he was elected secretary-treasurer of the Texas Pharmaceutical Association, and in 1918 he became president of the National Association of Retail Druggists. He owned drugstores in Munday and Wichita Falls.
He helped to establish the Texas Cowboy Reunion at Stamford in 1930 and served as historian, vice president, and president of the Reunion Association. He was author of Cuz (1922) and "Range Poems" in Lona Shawver's Chuck Wagon Windies (1934). He also wrote numerous poems, ballads, and articles that appeared in pharmaceutical journals and Texas Cowboy Reunion publications. He died in Dallas on February 6, 1942.
