October 13, 1966 –
The sixth episode of Star Trek, Mudd’s Women premiered on this date. In it, The Enterprise picks up a traveling con man, Harry Mudd, and his “beautiful” female cargo; the females seem to have a strange effect on the male crew.
This is the first episode in which the Enterprise’s power source is named, however, they are called simply “lithium crystals“, and not “dilithium” as was done in all later episodes of this and all later incarnations of Star Trek.
