The Bluetooth Symbol


The Bluetooth symbol has its origins in the story of a medieval King of Denmark, Harald Gormsson.  Harald is referred to in several Norse chronicles as Blatand (Bluetooth) because of his love of blueberries which made his teeth go blue.

When his parents died he erected huge stones on their graves. These so called Jelling Stones are a UNESCO World Heritage Site because of their significance as a bridge between the rituals of Scandanavian paganism and the spread of Christianity under his reign.

One stone has a depiction of Jesus, and the other refers to Harald’s achievements in uniting warring tribes in Denmark and Norway.

In 1994 the Swedish electronics company Ericsson, wanted to create a wireless interface system that would allow mobile communications devices to link and share data over short distances wirelessly.

Ericsson invited several competitors to form a Special Interest Group to work on the project. During a preliminary meeting Sven Mathesso of Ericsson gave Jim Kardach of Intel, The Long Ships, a historical novel set in the court of Harald the Bluetooth.

Kardach found similarities between the ancient king’s quest for unity and the unifying goals of the Special Interest Group, and so the project was given the title, ‘Bluetooth.

In honour of the spirit of collaboration inspired by Harald Bluetooth, the interface logo was designed to incorporate the king’s initials (H and B).
