Hensley, George Washington

Born in Calaveras County in 1857, George Washington “Doc” Hensley was the seventh son of pioneer parents who crossed the plains by ox team in 1853. After losing his initial sheep business to the severe drought of 1877, he worked in lumber, draying, and livery stables before establishing a well-boring business in 1888. Over thirty years in the trade, Hensley became a regional pioneer in well-drilling, installing the first irrigation pumping plant in Fresno County and inventing a specialized well-perforator that gained widespread use.

Alongside his well-boring achievements, Hensley drilled the first oil well in Kern County’s Kern River District and co-owned a half-section stock ranch with his brother in Madera County. Married to Annie Pennington, he raised six children in Fresno while maintaining an active presence as a charter member of the local Knights of Pythias. His innovative approach to water development helped revolutionize agricultural irrigation practices across Central California.
