Robert Langdon

Robert Langdon is the creation of novelist Dan Brown. The star of the books Angels and Demons (2000) and The Da Vinci Code (2004), Langdon is a rather dashing scholar and a professor of religious symbology at Harvard University. In Angels and Demons he tangles with a secret society known as the Illuminati, and in The Da Vinci Code he investigates a murder in the Louvre and discovers mysterious clues leading to the Catholic Church, Jesus and Mary Magdalene, and Leonardo Da Vinci. Langdon is played by actor Tom Hanks in the 2006 film of The Da Vinci Code; his colleague, the French cryptologist Sophie Neveu, is played by Audrey Tautou.

Extra credit: In The DaVinci Code, Robert Langdon is described as looking like "Harrison Ford in Harris tweed"... According to Angels and Demons, Langdon was "a varsity diver in prep school and in college"... In real life there is no professorship of religious symbology at Harvard; Brown invented the position for his tales.
