William M. Evarts

William Maxwell Evarts (February 6, 1818February 28, 1901) was an American lawyer and statesman from New York who served as U.S. Secretary of State, U.S. Attorney General and U.S. Senator from New York. He was renowned for his skills as a litigator and was involved in three of the most important causes of American political jurisprudence in his day: the impeachment of a president, the Geneva arbitration and the contests before the electoral commission to settle the presidential election of 1876.

During the presidency of Rutherford B. Hayes, the reform-minded Evarts was an active member among the "Half-Breed" faction of the Republican Party, which emphasized support for civil service reform, bolstering opposition towards conservative "Stalwarts" who defended the spoils system and advocated on behalf of Southern blacks.
