Dan Brown, born as Daniel Gerhard Brown on June 22, 1964, is an American author renowned for his thrilling novels, notably the 2003 bestseller, The Da Vinci Code. Brown's novels are characterized as treasure hunts set within a 24-hour timeframe, interwoven with recurring elements of cryptography, keys, symbols, codes, and conspiracy theories. His works have been translated into 57 languages and have sold over 200 million copies worldwide. Brown has also seen three of his novels, Angels & Demons, The Da Vinci Code, and Inferno, adapted into films, with The Lost Symbol being turned into a television show.

The central character in many of Brown's books, Robert Langdon, traverses through plots that frequently delve into Christian themes and historical fiction, sparking controversy. However, Brown clarifies on his website that his books are not anti-Christian. He describes himself as on a "constant spiritual journey," and regards The Da Vinci Code as "an entertaining story that promotes spiritual discussion and debate," suggesting it could serve as "a positive catalyst for introspection and exploration of our faith."

In 2005, Brown was named one of the 100 Most Influential People in the World by TIME Magazine, which attributed to him the revival of interest in Leonardo da Vinci and early Christian history, increased tourism to Paris and Rome, and a surge in membership in secret societies, among other impacts.
