Robert Van Kampen was the inventor of the three-quarters rapture theory in the late 1970s. According to one who was there, he first eliminated pretribulationism and then excluded posttribulationism. Thus, he had to come up with another view. That view is what he called the “pre-wrath” rapture theory. That title is a misnomer, since pretribulationism is 100% pre-wrath. If we follow consistency in labeling, Van Kampen’s view should be called the three-quarters rapture position, since he teaches that the church will be raptured somewhere in the middle of the last three and a half years of the 70th week of Daniel. Van Kampen spent a number of years searching for an advocate of his newly developed viewpoint until he was finally able to persuade Marvin Rosenthal to adopt and champion his new theory. I have a friend who was interviewed extensively by Van Kampen (in the 80s) for the pastorate of the church he attended in the Chicago area. My friend spent hours on the phone with Van Kampen, as he tried to convince him of his strange rapture view. In the end, my friend could not agree with Van Kampen. It was clear that Van Kampen was searching for someone to champion his rapture position. Rosenthal wrote a book called The Pre-Wrath Rapture of the Church, which was published by Thomas Nelson in 1990. Later Van Kampen came out with his own book called The Sign (three editions, 1992, 1999, 2000) from Crossway Books. He then had published The Rapture Question Answered: Plain and Simple (1997) with Revell.
