Ladislav Pelc is the current Prehumous Professor of Morbid Bibliomancy. He is unusual for a wizard in that he has no beard of his own but wears a false beard when in public. He resides in a small office in the Unseen University where he is currently working on a device to identify the reading needs of all visitors to the Library.
This character is named after a real person. In 2002, a flood destroyed Divadlo v Dlouhé, a theater in Prague, Czech Republic, which plays dramatizations of Terry Pratchett's novels. Terry Pratchett then suggested a benefit auction for reconstruction of the theater and Ladislav Pelc donated the highest sum in the auction.
In some medical contexts PELC stands for Palliative and End of Life Care. Appropriate for a wizzard that is looking after dead comrades.
