Hal Lindsey (b. 1930 Houston, Texas) started his career as a tugboat captain. He then became an evangelical and a best-selling author. His first book The Late Great Planet Earth (1970), according to the New York Times, was "the number one best-selling book of the 1970's."
He is famed and sought-after for his Chritian scripture-based prophecy. In his 1983 book The Rapture he recounts that in 1956 during a period of religious doubt he participated in a meeting with Jack Blackwell, then a young minster, who discussed biblical prophecy. He soon became convinced that current events are governed by the will of God in ways that interlock with biblical scriptue.
