Where did grok originate?

Grok originated in the 1961 sci-fi novel Stranger in a Strange Land, which was written by Robert A. Heinlein. The novel's protagonist, Valentine Michael Smith, was a human who was raised on Mars. Valentine used several Martian words, one of which was grok.

Those who enjoyed Heinlein's book began using grok in the same way Valentine did. (Or at least similarly. Heinlein never provided a specific definition for grok, but fans have decided that they grok what the word means.) Grok is now commonly used and recognized among nerds and geeks, as well as members of the 1960s counterculture movement.
