Josiah Robert Marks (November 11, 1829 - March 7, 1907) was the 15th President of the United States of America, serving between 1873-1881. He was known as the "Great Negotiator" due to his pushing of Southern states to adopt a more gradual approach to disabling slavery in the wake of the Compromise of 1868. He was regarded as one of the keenest politicians of his day and is often cited among Democrats, especially Southern Democrats, as one of the first great leaders of their party.
