A Vietnam War veteran, Campbell was honored by the Sox for his service during the July 31 game against the New York Mets as their "Hero of the Game."
In the second inning, Campbell was honored on the field while his Marine Corps bio was displayed on the scoreboard.
"It's a humbling experience to see 25,000 people standing and clapping and looking at you, and you're thinking 'What am I doing out here?'" Campbell said. "I'm an average guy. There were many young men that came home like I did. There were a lot of men that didn't come back."
Campbell suspected something was up when his wife and son recently started asking questions about what years and units he served in in Vietnam. His family made applications to the White Sox on Campbell's behalf, and an invitation was extended.
Campbell was able to celebrate his moment with 19 family members, including his four children and all but two grandchildren. He also had his grandfather with him, in spirit.
"I took a picture with me that belonged to my grandfather from the 1906 World Series. I have kept it all these years, I'll pass it on to my son and hopefully he will pass it on to his son," Campbell said. "It was almost a feeling that my grandfather was with me."
Campbell, who graduated from Hinckley-Big Rock High School in 1963, joined the Marine Corps out of high school on a 120-day delay program. He was assigned to a battalion in Camp Pendleton, where he trained for four months. From there Campbell went overseas, a 13-month tour of duty in Okinawa, Japan and the Philippines. He floated off the coast of Vietnam on the USS Princeton for a short time before rotating back to the U.S.
He joined the 3rd Battalion, 1st Marines, training men that would go over to Vietnam, entitled to stay in the states six months, before learning that he was extended by the President four months. Campbell went to Vietnam in late spring 1965.
"I made the decision that I would stay with my battalion. I was a squad leader of mortars that moves with the infantry; your job is to support them when needed," Campbell said. "I felt I was well trained, I went back, we trained for about four months and then went to Vietnam."
Campbell had seven or eight combat operations in the first 90 days, and a few more thereafter before he was rotated back to the U.S. in August of 1966.
He went to college on the GI Bill, graduated from Aurora College, now Aurora University, in 1966 and student taught in Oswego in 1971. He was then hired in Naperville and spent 30 years teaching U.S. history at District 203's Jefferson Junior High while coaching football and track.
"I wanted to be a history teacher since I was a kid," Campbell said. "As a kid I'd sit with my grandparents and watch Walter Cronkite 'You are There' documentaries.'"
