Drummond Ranch, in the Osage County city of Pawhuska, Oklahoma, began through the 1886 settling of Frederick Drummond, and led to the establishment of a trading company before his son, Roy, began ranching in 1913. By the 1980s, the surviving brothers and their descendants owned and managed over 200,000 acres in Oklahoma and parts of Kansas.
The Drummond sons, Roy, Jack and Frederick Jr., all attended college to help write ranching history within the towns of Osage County. After Roy began ranching in 1913, his brother Jack started ranches in Marshall and Osage counties. Following his education at Oklahoma A&M College and Harvard Business School, Frederick Jr. used his skills and advanced education to start two additional cattle ranches in Osage County during the Great Depression. At the time of his death in 1958, these two ranches sprawled across more than 25,000 acres.
Ranch operations were passed down to Frederick Drummond III, who earned degrees in business and banking from Oklahoma State and Stanford universities. A member of the Texas and South Western Cattle Raisers Association since he was seven years old, his life-long farming knowledge and banking experience left him well-equipped to lead and operate the ranch. In 2002, he began training his son, Ford, to lead the fourth generation of Drummond ranchers.
