After Abraham Lincoln's assassination, William Herndon, his former law partner, began exhaustive research on what became "the most influential biography of Lincoln ever published." Herndon, determined to learn all he could about his subject, initiated an extensive correspondence with people who had known the late president. In Herndon on Lincoln: Letters , Rodney O. Davis and Douglas L. Wilson collect the fruits of those exchanges. This invaluable resource offers the story of Lincoln's life and career as a lawyer, Republican Party founder, and candidate for office, rendered in Herndon's own authoritative and distinctive voice. A trove of primary source material, Herndon on Lincoln: Letters is a must for libraries, research institutions, and scholars of a towering American figure and his times.
