I've often wondered about this one--the creator of Bluetooth really reached into history to find a name for its product.
Harald Blåtand Gormsson was a Danish king who ruled from roughly 958 to 986. His nickname, Blåtand, means blue tooth, and there several possible origins for where it came from.
What we do know for sure is that he united several warring Danish tribes into a single kingdom. Bluetooth was a collaborative effort between the warring factions of Intel, IBM, Ericsson, and Nokia, hence the collaborative name that merged not only those factions, but also different forms of tech into one communicative web.
The Bluetooth logo is even a combination of the norse runes for H and B, Harald's initials.
