History & Origin

Thor takes its meaning, 'thunder', directly from the Norse thunder god, written Þórr in Old Norse. The name carries that mythological weight straight into everyday use, which is much of its appeal.

It links to related forms across the Germanic world: the simpler Tor, the Old English Þunor, and Donar and Þunraz from neighboring traditions. Explorer Thor Heyerdahl (1914 to 2002), of the Atlantic raft voyages, is among the best-known to bear it.
