Strackman Lux

Strackman Lux was the grandson of Felman Lux, the human who built the Library.

Technically, Charllote Abigail Lux (CAL), The Library computer, was his aunt.

Biography
After the library computer locked down the Library it took three generations of the Lux family to decode the seals. Strackman assembled an expedition to find out what had gone wrong. He travelled to the planet with Professor River Song and other archaeologists.

He was the apparent head of the Felman Lux Corporation at the time of the expedition to the Library. His personal assistant was Miss Evangelista. (TV: Silence in the Library)

At first his intentions seemed to be protecting his family's patent for the Library. Later, however, it became apparent that he was motivated by familial concern for Charlotte Lux (CAL).

He was the only member of the expedition not to die. (TV: Forest of the Dead)
