Charles Curtis (1860-1936) was a Kansas lawyer and politician who rose from county government to the U.S. House, Senate, and Republican Senate leadership. He became Herbert Hoover's vice president in 1929 and presided over the Senate during the first years of the Great Depression. Of Kaw ancestry through his mother, Curtis remains historically notable as the first person with significant Native American ancestry to serve as vice president.

Charles G. Dawes (1865-1951) was an Ohio-born lawyer and Chicago banker who became comptroller of the currency and later a leading figure in international economic reconstruction after World War I. His work on the Dawes Plan earned him the 1925 Nobel Peace Prize, and he subsequently served as Calvin Coolidge's vice president from 1925 to 1929. Afterward, Dawes served as U.S. ambassador to the United Kingdom before returning to Chicago, where he died in 1951.

Warren G. Harding (1865-1923) was the 29th president of the United States, serving from 1921 until his death in 1923, and was elected on a promise to restore stability and “normalcy” after World War I. Harding promoted tax cuts, reduced government spending, business growth, immigration restrictions, and arms limitation, while his administration was overshadowed by scandals.

John N. Garner (1868-1967) was a Texas lawyer who spent three decades in the House of Representatives and eventually became Speaker. He served as Franklin D. Roosevelt's vice president for eight years but broke with Roosevelt over important New Deal policies and challenged him for the Democratic nomination in 1940. Garner retired to Texas and lived until 1967, dying shortly before his ninety-ninth birthday.

Calvin Coolidge (1872-1933) was the 30th President of the United States, serving from 1923 to 1929. A staunch advocate of limited government, low taxes, balanced budgets, and business growth, Coolidge became one of the leading symbols of the conservative politics of the 1920s. His legacy remains debated over the role his policies played in the economic conditions that preceded the Great Depression.

Herbert Hoover (1874-1964) was the 31st president of the United States, a self-made mining engineer, businessman, and humanitarian. His presidency was dominated by the onset of the Great Depression, and his mixed policies for stabilizing the economy. After leaving office, Hoover remained an influential critic of the New Deal and devoted much of his later life to humanitarian work, government reform, and defending the principles of limited government and individual responsibility.
