In 2261, Professor Crater and his wife, Nancy arrived on planet M-113, and established an archaeological dig around some of the ruins on the planet. Over the next four years they exported many fascinating discoveries of the planet, but in 2265, the number of items being exported dwindled immensely when Nancy was killed by the last remaining "salt vampire", although this was not discovered until 2266. In the novelization of this episode, entitled "The Unreal McCoy" by James Blish, Professor Crater was referred to as Bierce.
