Og Mandino

Augustine "Og" Mandino II was an American author best known for his bestselling book The Greatest Salesman in the World.

Born in 1923, Mandino's life took a dramatic turn after his mother's sudden death.

He served in the U.S. Army Air Corps during World War II, flying bombing missions over Germany.

Post-war struggles led him to alcoholism and near-suicide.

A chance encounter with self-help books in a library changed his life, inspiring him to overcome his addiction and become a successful writer.

Mandino's works, influenced by the Bible and other motivational authors, have sold over 50 million copies and been translated into more than 25 languages.
