They were written in 1916 by the Rev. William J. H. Boetcker, a Presbyterian clergyman and pamphlet writer. In 1942, a group called the Committee for Constitutional Government gave out a great many leaflets entitled "Lincoln on Limitations" that contained on one side a real Lincoln quote and on the other side the 10 Boetcker statements. Boetcker was credited with his statements on the leaflet, but their proximity in print to one real quote by Lincoln, plus the title of the leaflet, led people to think that Lincoln had said the ten listed statements. They were repeated in many printed sources, and are still regarded by many as authentic Lincoln quotes. Carl Sandburg, Lincoln's most famous biographer, dismissed them as spurious.
