What is the peacetime occupation of Captain Miller in the film, "Saving Private Ryan"?

Captain John H. Miller (portrayed by actor Tom Hanks) was a thirty year old American serving in the 2nd Rangers Battalion of the U.S. Army during World War II. He is the protagonist of the 1988 film, "Saving Private Ryan."

Miller would not tell much about his life prior to World War II. Before joining the Army, John Miller had been employed at Thomas Alva Edison High School in Addley, Pennsylvania. He had taught English composition since 1933. Miller was married and was also the coach of the local baseball team in the Spring each year.

Miller and Corporal Upham had an agreement to let a bet the whole company made go to $500 before Miller would tell Upham about his life before the war. The two could split the $500 reward payout and not $1000 as Upham suggested. Also it is interesting that Miller is never shown with a wedding ring on his finger. One of the limited facts that he is married is made known.
