with all due respect but his name wasn`t Copernicus but Kopernik. It left to him from his father and grandfather.

When famous Serbian inventor and scentist Nikola Tesla startet to get post letters adressed on the name Nicolas (americanized), he refused to receive letters. He insited that his name is Nikola, not Nicolas
