English: John George Nicolay ( February 26, 1832, Essingen, Rhineland-Palatinate – September 26, 1901) burried at Griggsville Cemetary in Griggsville, IL was an American (German-born) biographer of Abraham Lincoln. In 1838, he immigrated to USA with his father. In 1861 Lincoln appointed Nicolay to be his private secretary, which was the first official act of his new administration. Nicolay served in this capacity until Lincoln's death in 1865. Several years after, Nicolay and John Hay, who had worked alongside Nicolay as assistant secretary to Lincoln, collaborated on the official biography of the 16th President. The resulting biography took up several volumes and for many years was considered a definitive resource on Lincoln and his times.
