This weekend was a conference that centered around Ellen G White (1827-1915), the co founder of the Seventh-day Adventist church. Ellen G White is an important figure in 19th century American religion and in American religion as a whole.
The Seventh-day Adventist church was founded in America in the 19th century at the the same time as the Church of Jesus Christ of Latter-day Saints and the Church of Christ, Scientist.
Information from the conference will be published in a book, scheduled to come out in summer 2010. You can learn more about the participants in this conference at http://www.ellenwhiteproject.com/.
