Thomas Alva Edison High School
Prior to serving with the U.S. Army during World War II, John Miller was an English teacher at Thomas Alva Edison High School in Addley, Pennsylvania. The school's namesake, Thomas Edison, was an inventor known for such creations as the phonograph and the incandescent light bulb. Edison was a prolific inventor and had over 1000 patents before his death in 1931.
Although there doesn't appear to be a Thomas Alva Edison High School in Miller's home state of Pennsylvania, there are a variety of them scattered across the United States.
