Robert Langdon

Professor Robert Langdon is a fictional character created by author Dan Brown for his novels Angels & Demons (2000), The Da Vinci Code (2003), The Lost Symbol (2009) and Inferno (2013). He is a Harvard University professor of religious iconology and symbology (a fictional field related to the study of historic symbols, which is not methodologically connected to the actual discipline of Semiotics).

Known for a brilliant problem-solving mind and his genius, Langdon has an eidetic memory. As professor at Harvard University, he teaches religious iconology and the fictional field of symbology. As a hobby it is specifically mentioned that Langdon is a great swimmer and swam laps (50) daily, a “morning ritual,” at Harvard’s athletic facilities (hence the lap swimming scene in the Angels and Demons movie). Langdon also mentions he was raised a Catholic, but that he will never understand God; in A&D, he mentions to the Camerlengo that faith is a gift he has yet to receive.
