Ralph Henry Uff, 91, of Allentown, died Feb. 23, 2025, surrounded by his family. He was a devoted husband to the late Catherine (Roma) Uff for almost 70 years. Born in Allentown, he was the son of the late Ernest F. Uff Jr. and Lois (Fieldhouse) Uff.

As a 101st Airborne United States Army SP4, he served during the Korean War in the Army Security Agency providing signal intelligence and security information.
