Detailed here:
Tim LaHaye was born in Detroit, Michigan. His mother was the former Margret Palmer and his father, Frank LaHaye, was a Ford auto worker who died in 1936 of a heart attack. His father's death had a significant influence on LaHaye, who was only nine years old at the time. He had been inconsolable until the minister at the funeral said, "This is not the end of Frank LaHaye; because he accepted Jesus Christ, the day will come when the Lord will shout from heaven and descend, and the dead in Christ will rise first and then we'll be caught up together to meet him in the air." LaHaye later said that, upon hearing those remarks, "all of a sudden, there was hope in my heart I'd see my father again."
Tim LaHaye passed away yesterday at the age of 90.
