Yes you read that right, SP3RN is considered the patron saint of amateur radio. You see SP3RN belonged to a Polish Conventual Franciscan Friar named Maximilian Kolbe who was arrested by the SS in WWII and sent to Auschwitz for, among other things, using his amateur station to report on the atrocities being perpetrated by the Nazis on the Polish people. He would later volunteer to be sent to starve to death in place of another prisoner. He would be canonized in 1982 as a martyr by Pope John Paul II.
