Early life Levy's family emigrated from Montreal, Canada. His father, a decorated World War I veteran, ran a small business on the South Side of Chicago. He graduated from South Shore High School in Chicago in 1943. Following graduation, he enlisted in the Army Air Forces and spent the remainder of World War II in the military; Levy was discharged from the army shortly after the war ended. Though he was known to use historical examples to inspire his teams, Levy corrected those who used war and combat metaphors to describe football games by telling them that he actually fought in a war and that football and war were in no way comparable.[1] Referring to the Super Bowl, he once said "This is not a must-win; World War II was a must-win".

I'm paraphrasing.
Levy has the unique distinction of being at two World Series involving the Chicago Cubs. After being discharged from the military, he made it to the 1945 World Series. In 2016, he was an honored guest at the World Series.
Retired US Supreme Court Justice John Paul Stevens has attended the World Series at Wrigley Field in 1929 (the first time that Wrigley hosted the Series), 1932 and 2016.
