This research paper uncovers various physiological aspects of who Jim Morrison was as a person, not just as the rock star. As such, the paper discusses and sites examples on how he became that person from Jim's childhood experiences, social motives, home environment and interaction with his family, his education and drug use which eventually led to his death.
From the Paper:
"James Douglas Morrison was born in Melbourne, Florida December 8, 1943 to Clara and Steve Morrison. Jim was raised by his strict, conservative parents but would grow to express drastically different views than those taught to him. Clara was a housewife and daughter of a lawyer. Steve was an officer in the U.S. Navy. Jim had two younger siblings: a brother, Andy, and a sister, Anne. Anne was the youngest of the three. Because of the position Jim's father had in the military, Jim's family was required to move quite often due to transfer orders. "
