Jón Gnarr

Jón Gnarr is an Icelandic actor, comedian, and politician who served as the Mayor of Reykjavík from 2010 to 2014. Born Jón Gunnar Kristinsson, Jón legally changed his middle name in 2005 to the way his mother pronounced it when he was a boy. He prefers to be addressed as Jón Gnarr as he does not wish to carry his father's name. Under national law overseen by the Icelandic Naming Committee, he had not been allowed to legally drop "Kristinsson" from his name as seen on his passport until 2015.
