William Henry Seward, Sr. (May 16, 1801 – October 10, 1872) was the 12th Governor of New York, United States Senator and the United States Secretary of State under Abraham Lincoln and Andrew Johnson. A determined opponent of the spread of slavery in the years leading up to the American Civil War, he was a dominant figure in the Republican Party in its formative years, and was widely regarded as the leading contender for the party's presidential nomination in 1860 – yet his very outspokenness may have cost him the nomination. Despite his loss, he became a loyal member of Lincoln's wartime cabinet, and played a role in preventing foreign intervention early in the war. On the night of Lincoln's assassination, he survived an attempt on his life in the conspirators' effort to decapitate the Union government. As Johnson's Secretary of State, he engineered the purchase of Alaska from Russia in an act that was ridiculed at the time as "Seward's Folly", but which somehow exemplified his character. His contemporary Carl Schurz described Seward as "one of those spirits who sometimes will go ahead of public opinion instead of tamely following its footprints."
