Divisions John Norton Loughborough (January 26, 1832 – April 7, 1924) was an early Seventh-day Adventist minister.

Born in Victor, New York, Loughborough began preaching about the Second Coming of Christ at seventeen years of age, renting a church to deliver his lectures.

[1] He was involved in the Seventh-day Adventist movement from its early days, having been called to preach by Ellen White in 1852.

In 1878 Ellen White told him that his work for the church "must be made to tell for its full value and that he will have to preach the message."

He compiled the first Adventist medical book, Handbook of Health (1868), which excerpted material from Sylvester Graham, James Caleb Jackson, Russell Thacher Trall and others.
