Dan BrownDaniel Gerhard Brown (born June 22, 1964) is an American author best known for his thriller novels, including the Robert Langdon novels ''Angels & Demons'' (2000), ''The Da Vinci Code'' (2003), ''The Lost Symbol'' (2009), ''Inferno'' (2013), and ''Origin'' (2017). His novels are treasure hunts that usually take place over a period of 24 hours. They feature recurring themes of cryptography, art, and conspiracy theories. His books have been translated into 57 languages and, as of 2012, have sold over 200 million copies. Three of them, ''Angels & Demons'', ''The Da Vinci Code'', and ''Inferno'', have been adapted into films, while one of them, ''The Lost Symbol'', was adapted into a television show.
The Robert Langdon novels are deeply engaged with Christian themes and historical fiction, and have generated controversy as a result. Brown states on his website that his books are not anti-Christian and he is on a "constant spiritual journey" himself. He claims that his book ''The Da Vinci Code'' is simply "an entertaining story that promotes spiritual discussion and debate" and suggests that the book may be used "as a positive catalyst for introspection and exploration of our faith."
