William Miller 
Evidence from Scripture and History of The Second Coming of Christ [EPUB ebook] 

The Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief regarding the future (or past) return of Jesus after his ascension to heaven about two thousand years ago. The idea is based on messianic prophecies and is part of most Christian eschatologies.
William Miller (February 15, 1782 – December 20, 1849) was an American Baptist preacher who is credited with beginning the mid-19th-century North American religious movement known as Millerism. After his proclamation of the Second Coming did not occur as expected in the 1840s, new heirs of his message emerged, including the Advent Christians (1860), the Seventh-day Adventists (1863) and other Adventist movements.
