Maybe you have already read Inferno, The Da Vinci Code or Angels and Demons. Notable author and writer Dan Brown has achieved an array of fictional books through out his tenure. However, not many know that outside his books, he used to teach Math.

The thriller fiction writer, born in New Hampshire in 1964, and according to Ranker, a novelist and actor, too, started out with puzzles. As a young man he already had interests in secrets and puzzles. In his home, there were codes and ciphers. These were tied together with mathematics, music and language. All things that his parents know. His mother was a choir master and his father a math teacher.

His father would give him clues like a treasure map for Christmas instead of presents. He'd find clues around the house and he'd eventually find the gifts. Sounds familiar? It's a scene in The Da Vinci Code.

He attended Philips Exeter and then he attended Amherst College. In a few years, he went abroad to Seville, Spain. There he enrolled in art history in the University of Seville. He went back to Amherst and graduated in 1986.

But he didn't start writing then and there. He tried his hand with music. He used a synthesizer for his works. A few years later, he moved to Hollywood to pursue a singer and song writer career. To pay his bread and butter, he taught classes at Beverly Hills Preparatory School. In 1993, he went back to New Hampshire and taught English at Philips Exeter. He also taught Spanish classes at Lincoln Akerman School.

When asked about Shakespeare's literature: "I didn't understand how funny this play Much Ado About Nothing truly was until I became an English teacher and had to teach it. There is no wittier dialogue anywhere," says Dan Brown.
