HARALD the BLUETOOTH--DENMARK
A Viking king of the 10th century, now echoes in the modern world as a symbol of seamless connectivity. His legacy of unifying many kingdoms to having his name unifying various modern devices, serves as a testament to the impact of historical figures on our contemporary lives.
Harald Gormsson the Bluetooth possibly got his nickname from having a tooth that was "dark" or "bluish". It was also said that he REALLY liked blueberries and stained his teeth! His name's initials are the Bluetooth icon rune. The B in the rune (icon) stands for Blatand meaning blue or dark tooth. Google him!
