Abraham Lincoln II (August 14, 1873 - September 7, 1967), better known as simply Jack, or Jack Lincoln was the grandson of President Abraham Lincoln, son of Robert Todd Lincoln, and the 26th and 28th President of the United States. He was also the 23rd Governor of Illinois, and is the only U.S. president to have served four terms in office, as well as the only president to have served multiple non-consecutive terms.
Born in Chicago in August 1873, Jack grew up in a radically different nation than had existed prior to the Civil War, and from an early age gained an interest in politics, seeking to emulate his grandfather and namesake. His father Robert was Secretary of War, first under Ulysses S. Grant and then James Blaine from 1873 to 1881, and as Blaine's vice president from 1881-85, galvanizing young Jack's future on the political scene. Completing governmental and law studies at Harvard in 1895, Jack was first thrust onto the national political scene in August 1896, when he gave a persuasive speech on behalf of future President William McKinley in Charleston, Virginia. In 1904, Jack ran for and won the governorship of Illinois with the endorsement of incumbent Governor Richard Yates, Jr., eventually serving two terms, from 1905 to 1913. He was voted to the US House of Representatives for Illinois' 19th District in 1913, a position he served in until 1924, when he resigned after receiving the Republican nomination for president.
Jack served his first two terms as a peacetime president, from 1925 to 1933, after which he entered into semi-retirement with his wife Jeanne, occasionally donating their time and effort helping to combat the Great Recession of 1933-39. In the hard-fought election of 1940, Jack became the first president to serve more than two full terms, and the oldest since William Henry Harrison exactly a hundred years prior. He led the United States through World War II, and was re-elected for the final time in 1944. When he left office for the final time in 1949, Jack officially became the longest-serving president in US history. For the remaining eighteen years of his life, Jack and his wife retired to their estate outside Denver City, Jefferson; he died at the age of 94 in September 1967, and was buried on the estate grounds.
