Have you ever wondered about the origin of the word ‘Bluetooth’? Not only was the Swedish company Ericson deeply involved in the development of Bluetooth, but the name originates from a Scandinavian Viking – King Harald “Blåtand” Gormsson. 

King Harald “Blåtand” Gormsson was born in Denmark during the 10th century. Today, he is primarily known for bringing Christianity to Denmark and spreading it throughout the rest of the Scandinavian region.

The Vikings, who were at the time pagan, faced a whole new religion and along with it a change in culture. Traditions within the culture which could have been considered barbaric or violent by outsiders changed thanks to King Harald and the rising popularity of Christianity. Fittingly, King Harald was also the first Scandinavian king to get baptized.

How Bluetooth got its name

King Harald was not only famous for bringing Christianity to Scandinavia hence ending an old era, and starting a new one for the Vikings. The king was also known for uniting countries.

Jim Kardach from Intel, which was one of the corporate members in the Bluetooth SIG, had read about the Scandinavian Viking and was inspired to name his new invention “Bluetooth”. He made the connection when learning that King Harald had united Denmark and Norway.

“King Harald Bluetooth was famous for uniting Scandinavia, just as we intended to unite the PC and cellular industries with a short-range wireless link,” Kardach wrote in an article for EE Times.

“Bluetooth” was initially supposed to be a temporary name until they had come up with something better, but it became so popular with the public and the press, that Jim Kardach and his team at Ericson decided to keep the name.

The Bluetooth symbol is a combination of Harald Bluetooth’s initials H and B written in Scandinavian runes.

Now to the question we know you’ve been asking yourself all along. Why was his name Blue Tooth? (Swedish, Blå Tand)
There are a few theories regarding his rather uncommon name. One is that he loved blueberries, another one is that he had a bad tooth which had started to rot so badly it was blue. A third theory is that he often wore blue clothes which was the color of royalty at the time.

Whichever the truth may be — we love the fact that an old Viking continuous to live in the future through technology.
