A meticulously documented book, based on ten years of dedicated research, is both a biography of an able if now forgotten Supreme Court Justice and Senator, one of Lincoln's strongest supporters, and an account of mid 19th century Illinois politics. David Davis, Maryland born, educated at Kenyon College, moved to Pekin, Illinois, where he opened a law office, married and became Lincoln's lifelong friend. A huge man with a fine judicial mind, Davis was named Circuit Court Judge in 1848 and played an increasingly important part in anti-slavery, anti-Douglas, pro-Lincoln politics. Becoming Lincoln's manager in 1860, he was largely responsible for his nomination and was an adviser during his presidency. He later was named to the Supreme Court by Lincoln and then became U.S. Senator from Illinois.... This endlessly detailed but often surprisingly readable book is certainly the definitive biography of Judge Davis and important as reference in the fields of American legal and political history.
