Chaim Herzog, the 6th President of Israel, was nicknamed "Vivian". Let us explain.
Herzog, who was born in Ireland, fought in the British army during World War II. His fellow soldiers could not pronounce his first name. So, Vivian!
You see, "Chaim" comes from the Hebrew chayyim, or "life". And "Vivian" comes Latin vivus, "alive"! So, Vivian!
Herzog made his way to Israel, joined the IDF, opened a law firm, was appointed the ambassador to the UN, and became president. The nickname stuck. So, Vivian!
Seriously, Brits? Vivian? "Chaim" is really not that hard to pronounce...
