“During WWII musicians were recruited for code breaking.”
I’m retired now, but I worked for the Univ. of IL (UIC) Math Dept, directly for the Head. One of our Profs, and my good buddy, was an older gent who was a Brit. During WWII, as a then young wiz kid Mathematician, he worked as a code breaker in the U.K. He was also a top notch pipe organist, and played in various Oak Park, IL churches (OP is where Frank Lloyd Wright had his architecture studio and he built many Prairie Style homes there). Ernest Hemingway was also from Oak Park; it’s where my parents and my sisters and I lived until we moved further out in the suburbs. Great historical town just outside Chicago.
Oliver mostly played in his beautiful Episcopal Church in Oak Park. So, a great musician, and a great mathematician, and a great friend of mine in the Dept. As an aside, Oliver was also a conservative, and there was a secret network of us, many of whom would drop in at various times during the day to my office to get their dose of political chit chat (we were surrounded by primarily liberal political enemies, lol). Oliver is deceased, but he fondly lives on in my memories.
We are doing our possibles to bring our local Catholic parish back up to par -- they jettisoned the entire musical tradition at Vat II (idiots! they invented it!)
I was kidding around with my former choirmaster, and said, "Hey! You stole our music!" - he didn't miss a beat: "You weren't using it."
