Albert Benjamin "Happy" Chandler, Sr. (July 14, 1898 – June 15, 1991) was a politician from the US state of Kentucky. He represented the state in the U.S. Senate and served as its 44th and 49th governor. Aside from his political positions, he also served as the second Commissioner of Major League Baseball from 1945 to 1951 and was inducted into the Baseball Hall of Fame in 1982. His grandson, Ben Chandler, is currently a congressman from Kentucky's Sixth District.

A multi-sport athlete during his college days at Transylvania College, Chandler briefly considered a career in professional baseball before deciding to pursue a law degree. After graduation, he entered politics and was elected as a Democrat to the Kentucky Senate in 1928. Two years, later, he was elected lieutenant governor, serving under Governor Ruby Laffoon. Chandler and Laffoon disagreed on the issue of instituting a state sales tax and when Chandler, the presiding officer in the state senate, worked to block the legislation, Laffoon's allies in the General Assembly stripped him of many of his statutory powers. The tax then passed by a narrow margin. Knowing that Laffoon would try to select his own successor at the Democratic nominating convention, Chandler waited until Laffoon left the state – leaving Chandler as acting governor – and called the legislature into session to enact a mandatory primary election bill. The bill passed, and in the ensuing primary, Chandler defeated Laffoon's choice, Thomas Rhea. He then went on to defeat Republican King Swope by the largest margin of victory for a Kentucky gubernatorial race to that time. As governor, Chandler oversaw the repeal of the sales tax, replacing the lost revenue with new excise taxes and the state's first income tax. He also enacted a major reorganization of state government, realizing significant savings for the state. He used these savings to pay off the state debt and improve the state's education and transportation systems.

Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States, serving from 1969 to 1974. The only president to resign the office, Nixon had previously served as a US representative and senator from California and as the 36th Vice President of the United States from 1953 to 1961.

Nixon was born in Yorba Linda, California. After completing his undergraduate work at Whittier College, he graduated from Duke University School of Law in 1937, and returned to California to practice law. He and his wife, Pat Nixon, moved to Washington to work for the federal government in 1942. He subsequently served in the United States Navy during World War II. Nixon was elected to the House of Representatives in 1946 and to the Senate in 1950. His pursuit of the Hiss Case established his reputation as a leading anti-communist, and elevated him to national prominence. He was the running mate of Dwight D. Eisenhower, the Republican Party presidential nominee in the 1952 election. Nixon served for eight years as vice president. He waged an unsuccessful presidential campaign in 1960, narrowly losing to John F. Kennedy, and lost a race for Governor of California in 1962. In 1968, he ran again for the presidency and was elected.

Jack Roosevelt "Jackie" Robinson (January 31, 1919 – October 24, 1972) was an American baseball player who became the first black Major League Baseball (MLB) player of the modern era. Robinson broke the baseball color line when he debuted with the Brooklyn Dodgers in 1947. As the first black man to play in the major leagues since the 1880s, he was instrumental in bringing an end to racial segregation in professional baseball, which had relegated black players to the Negro leagues for six decades. The example of his character and unquestionable talent challenged the traditional basis of segregation, which then marked many other aspects of American life, and contributed significantly to the Civil Rights Movement.

In addition to his cultural impact, Robinson had an exceptional baseball career. Over ten seasons, he played in six World Series and contributed to the Dodgers' 1955 World Championship. He was selected for six consecutive All-Star Games from 1949 to 1954, was the recipient of the inaugural MLB Rookie of the Year Award in 1947, and won the National League Most Valuable Player Award in 1949—the first black player so honored. Robinson was inducted into the Baseball Hall of Fame in 1962. In 1997, Major League Baseball retired his uniform number, 42, across all major league teams.
