Being born in Switzerland an automatic American citizen is not hard to do if your father was naturalized in New York. But there's the problem of language. Fred learned, and forgot, English first, because his mother had been sent to London by the watch manufacturer Alfred Kurth. It was eight years before she could join her husband, and in that time the youthful Frederick abandoned the English language for a more useful Schwyzerduetsch (Swiss-German). But in New York the IHM nuns brought him back to English so effectively that he later became an English teacher.
As an author and later publisher, he banked on his experiences being a scoutmaster, a basketball coach, a baseball coach, a camp counselor, a religious novice, a college physics major (would be) and a public school English teacher. He's still open for whatever the good Lord sends.
