Both Stapleton and Lowry AFB have now been converted into Denver urban sprawl, but I graduated from a classified USAF technical school on Lowry in the early 1960s, when it was still a USAF Air Training Command base.
No question about that date; I married my wife nearly 58 years ago, and we newly-weds lived in Denver while I was attending school at Lowry...)
