Strackman Lux

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

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 one of the expedition not to die. (DW: Silence in the Library/ Forest of the Dead)
