Christianity • Protestantism Samuel Sheffield Snow (1806–1890) was a skeptic turned Millerite preacher who calculated that the return of Christ was to take place on October 22, 1844.
His teaching sparked what became known as the "Seventh-Month movement," which led to the Great Disappointment when Jesus did not return as expected.
He had even worked as an agent for the Boston Investigator, an avowedly atheistic newspaper.
He was converted to Christianity in 1839, as a result of reading a copy of William Miller's lectures that his brother had bought.
[2] On the 12th of August 1844 Snow said in Exeter, New Hampshire, that Jesus Christ would come back on the 22nd of October 1844.
