Principal of Hendersonville High during the Depression and World War II eras, he was both strict and kind and was described as “the man” who was law and gospel. Known affectionately as “Pop” among the students, but “Mr. Singley” to his face, he had respect from them and loved every child in school - good and bad. He secured several patents, one being the Singley Sanding Drum, a power woodworking accessory tool he invented while teaching mechanical drawing and manual training known today as “shop.”
