Born December 29, 1808, Andrew Johnson began his political career in Greeneville, Tenn. After serving as both alderman and mayor of Greeneville, Johnson successfully ran for a seat in the lower house of the state legislature in 1835. After serving three terms in the state Senate, Johnson moved to the United States House of Representatives, where he served for ten years, 1843-1853. He also served as Governor of Tennessee from 1853-1857. In the fall of 1857, he was chosen as a United States Senator.

In 1861, Johnson returned to East Tennessee to fight the surging secessionist movement, joining former political opponents such as William G. Brownlow, Thomas A. R. Nelson, Horace Maynard, and others in his support of the Union. After a June 8 referendum in which Tennesseeans voted for secession, Johnson returned to Washington to escape physical harm.

After the Federal capture of Forts Henry and Donelson and the occupation of Nashville in February 1862, however, President Lincoln sent Johnson back to Tennessee to serve as military governor, a position in which he was charged to restore civil government and bring the state back to the Union. In 1864, the Republicans nominated Johnson as Lincoln's running mate because of his staunch Unionism as a War Democrat. After Lincoln's assassination on April 14, 1865, Johnson was sworn in as the seventeenth President of the United States.

Johnson faced the difficult task of reconstructing the nation in the wake of the Civil War as he assumed the presidency. Johnson and Congress clashed over control of Reconstruction and, in 1868, the House Republicans in Congress impeached Johnson, the first president to face impeachment. Johnson's presidency was spared by a single vote in the Senate.

Following his tumultuous presidency, Johnson returned to Greeneville, eager for vindication. In 1874, he became the first former President of the United States to win a seat in the United States Senate. However, four months after taking his seat in the Senate, Johnson suffered a stroke and died on July 31, 1875. He was buried wrapped in a American flag with his head resting on a copy of the Constitution.

William Henry Seward was born to Samuel and Mary (Jennings) Seward in Florida, New York on May 16, 1801. He graduated from Union College in 1820 and was admitted to the New York Bar in 1822. He married Frances Miller on October 10, 1824, and the couple had five children. Seward practiced law in Auburn, New York before becoming involved in politics. He served as a member of the New York Senate (1830-1834) and as the Governor of New York (1838-1842) before representing New York in the United States Senate (1849-1861). In 1860, Abraham Lincoln appointed Seward Secretary of State. He served until 1869, during which time he advocated war with Spain and France to solidify the United States, protested against the outfitting of Confederate privateers in British ports, purchased Alaska (which, due to public opposition, was nicknamed "Seward's Folly" and "Seward's ice-box") from Russia for $7,200,000, and unsuccessfully attempted to acquire two islands in the Danish West Indies and annex Hawaii. Seward died in Auburn on October 15, 1872 and is buried in the Fort Hill Cemetery.
