George Bancroft who was asked by congress and did present A Memorial Address of Lincoln which can be found here. Bancroft was a democrat but opposed slavery so he moved to the Republican Party under Lincoln. He is the one who called Calvin " the father of America" and "He that will not honor the memory and respect the influence of Calvin knows but little of the origin of American liberty." Bancroft was a graduate of Harvard at age 17 and his life's work "which made him one of the best-known historians in the western world, is the multi-volume, monumental History of the United States, from the Discovery of the American Continent, covering the entire period down to 1787, which he revised two times in its entirety."-Conservapedia. "Among his best-known writings is the magisterial series, History of the United States, from the Discovery of the American Continent."-Wikipedia

After Harvard "he went to study in Germany where he received his doctorate from the Unversity of Gottingen. Bancroft capped off his education with European tour, in the course of which he sought out almost every distinguished man in the world of letters, science and art; among others, Goethe, Humboldt, Schleiermacher, Hegel, Byron, Niebuhr, Bunsen, Savigny, Cousin, Constant and Manzoni."-Wikipedia. Just for some background.

Getting back to President Lincoln "at Bancroft's request...Lincoln wrote out what would become the fourth of five known manuscripts of the Gettysburg address."-Wikipedia.
