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 had played dramatizations of Terry Pratchett's novels. Terry Pratchett suggested a benefit auction for reconstruction of the theater and Ladislav Pelc donated the highest sum in the auction so was immortalized in the novel Going Postal.
