Bluetooth

Harald Bluetooth Gormsson (Old Norse: Haraldr blátǫnn Gormsson, Danish: Harald Blåtand Gormsen) (probably born c. 935) was a King of Denmark and Norway. He was the son of King Gorm the Old and of Thyra Dannebod. He died in 985 or 986 having ruled as King of Denmark from c. 958 and King of Norway for a few years probably around 970. According to legend, he gained the nickname “Bluetooth” from his love of blueberries, which stained his teeth.

1000 years later, in 1994, Jim Kardach developed a system that would allow mobile phones to communicate with computers (at the time he was reading Frans Gunnar Bengtsson’s historical novel The Long Ships about Vikings and king Harald Bluetooth). Then Bluetooth was born. Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

The Bluetooth logo is a bind rune merging the Younger Futhark runes Runic letter ior.svg (Hagall) (ᚼ) and Runic letter berkanan.svg (Bjarkan) (ᛒ), Harald’s initials.
