Hadley attended Oklahoma A&M College from 1941-43 and 1946-49. He joined his brothers Harvey and Wesley at the Alpha Gamma Rho fraternity house and graduated with a B.S. and master’s in agronomy.
From January 1943 until Dec. 8, 1945, Hadley served in the Army Air Corps as an Aviation Cadet in World War II. He was awarded the American Theater Ribbon and World War II Victory Medal. He was truly part of America’s “greatest generation.”
Hadley’s first job was as a soils laboratory technician for the Soil Conservation Service. He was promoted to the position of soil scientist for the SCS in 1949 and moved to Guymon, where he served all three counties of the Oklahoma Panhandle, helping farmers learn good farming techniques to overcome the Dust Bowl years.
In April 1956, his friend, Royal Jackson, set Hadley up on a blind date with a young legal assistant who worked in Oklahoma City, Lois Marie Schroeder. They soon learned they were both from the Okarche area and both of their fathers had helped build the Lutheran Church in Okarche, the oldest in Oklahoma, and both played in the community band. Although their older siblings knew one another, Hadley and Lois had never met. It took quite a bit of convincing for Lois to leave her urban ways and agree to move to the Oklahoma Panhandle to marry Hadley, but she came to love that wide-open land as much as he did, marrying on Sept. 7, 1958, in Okarche in the church their fathers built. After a honeymoon to San Francisco, they returned to their careers in Guymon and she became pregnant with their first child, Teresa Ann.
Before Teresa was born, Hadley was promoted to a soil conservationist. The new family moved to Chickasha, then to Shawnee, where their son, John Hadley, was born, and finally to Purcell and Norman, where Hadley retired in 1980. Lois was diagnosed with aggressive breast cancer at a young age and Hadley was widowed in January 1987.
