Edgar C. Whisenant
Edgar C. Whisenant (September 25, 1932 – May 16, 2001), was a former NASA engineer and Bible student who predicted the Rapture would occur in 1988, sometime between Sept. 11 and Sept. 13. He published two books about this: 88 Reasons Why the Rapture Will Be in 1988 and On Borrowed Time. Eventually, 300,000 copies of 88 Reasons were mailed free of charge to ministers across America, and 4.5 million copies were sold in bookstores and elsewhere. Whisenant was quoted as saying "Only if the Bible is in error am I wrong; and I say that to every preacher in town," and "[I]f there were a king in this country and I could gamble with my life, I would stake my life on Rosh Hashana 88." 
Whisenant's predictions were taken seriously in some parts of the evangelical Christian community. As the date approached, regular programming on the Christian Trinity Broadcast Network (TBN) was interrupted to provide special instructions on preparing for the Rapture.
When the predicted Rapture failed to occur, Whisenant followed up with later books with predictions for various dates in 1989, 1993, and 1994. These books did not sell in quantity. Whisenant continued to issue various Rapture predictions through 1997, but gathered little attention.
