27.William Howard Taft

William Howard Taft (September 15, 1857 – March 8, 1930) was the 27th President of the United States (1909–1913) and later the tenth Chief Justice of the United States (1921–1930). He is the only person to have served in both offices.
Born in 1857 in Cincinnati, Ohio, into the powerful Taft family, "Big Bill" graduated from Yale College Phi Beta Kappa in 1878[2] and from Cincinnati Law School in 1880. He worked in local nondescript legal positions until he was tapped to serve on the Ohio Supreme Court in 1887. In 1890, Taft was appointed Solicitor General of the United States and in 1891 a judge on the United States Court of Appeals for the Sixth Circuit. In 1900, President William McKinley appointed Taft Governor-General of the Philippines. In 1904, President Theodore Roosevelt appointed Taft Secretary of War with the hope that he might groom Taft, then his close political ally, into his handpicked presidential successor.
Riding a wave of popular support for fellow Republican Roosevelt, Taft won an easy victory in his 1908 bid for the presidency.[3]
In his only term, Taft's domestic agenda emphasized trust-busting, civil service reform, strengthening the Interstate Commerce Commission, improving the performance of the postal service, and passage of the Sixteenth Amendment. Abroad, Taft sought to further the economic development of underdeveloped nations in Latin America and Asia through "Dollar Diplomacy". However, Taft often alienated his own key constituencies, and was overwhelmingly defeated in his bid for a second term in the presidential election of 1912.
After leaving office, Taft spent his time in academia, arbitration, and the search for world peace through his self-founded League to Enforce Peace. In 1921, after the First World War, President Warren G. Harding appointed Taft Chief Justice of the United States. Taft served in this capacity until shortly before his death in 1930. He is the only former president to administer the oath of office to another President and the only Chief Justice to serve with associate justices whom he had appointed to the court.

28.Woodrow Wilson

Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was the 28th President of the United States, from 1913 to 1921. A leader of theProgressive Movement, he served as President of Princeton University from 1902 to 1910, and then as the Governor of New Jersey from 1911 to 1913. WithProgressive ("Bull Moose") Party candidate Theodore Roosevelt and Republican nominee William Howard Taft dividing the Republican Party vote, Wilson was elected President as a Democrat in 1912.

In his first term as President, Wilson persuaded a Democratic Congress to pass major progressive reforms including the Federal Reserve Act, Federal Trade Commission Act, the Clayton Antitrust Act, the Federal Farm Loan Act and an income tax. Wilson brought many white Southerners into his administration, and supported the introduction of segregation into many federal agencies.[1]

Narrowly re-elected in 1916, he had full control of American entry into World War I, and his second term centered on World War I and the subsequent peace treaty negotiations in Paris. He based his re-election campaign around the slogan, "He kept us out of war", but U.S. neutrality was challenged in early 1917 when the German government began unrestricted submarine warfare despite repeated strong warnings, and tried to enlist Mexico as an ally. In April 1917, Wilson asked Congress to declare war. During the war, Wilson focused on diplomacy and financial considerations, leaving the waging of the war itself primarily in the hands of the Army. On the home front in 1917, he began the United States' first draft since the American Civil War, raised billions of dollars in war funding through Liberty Bonds, set up the War Industries Board, promoted labor union cooperation, supervised agriculture and food production through the Lever Act, took over control of the railroads, and suppressed anti-war movements. While he did not encourage the wave of anti-German sentimentsweeping the country in 1917-18, he did nothing to stop it.

In the late stages of the war, Wilson took personal control of negotiations with Germany, including the armistice. In 1918, he issued his Fourteen Points, his view of a post-war world that could avoid another terrible conflict. In 1919, he went to Paris to create the League of Nations and shape the Treaty of Versailles, with special attention on creating new nations out of defunct empires. In 1919, during the bitter fight with Henry Cabot Lodge and the Republican-controlled Senate over the U.S. joining the League of Nations, Wilson collapsed with a debilitating stroke. He refused to compromise, effectively destroying any chance for ratification. The League of Nations was established anyway, but the United States never joined. An intellectual—the only president with a PhD—he bitterly fought other intellectuals such as Roosevelt and Lodge. A Presbyterian of deep religious faith, Wilson appealed to a gospel of service and infused a profound sense of moralism into his idealistic internationalism, now referred to as "Wilsonian". Wilsonianism calls for the United States to enter the world arena to fight for democracy, and has been a contentious position in American foreign policy.[2]

31.Herbert Hoover

Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was the 31st President of the United States (1929–1933). Hoover was originally a professional mining engineer and author. As the United States Secretary of Commerce in the 1920s under Presidents Warren Harding and Calvin Coolidge, he promoted partnerships between government and business under the rubric "economic modernization". In the presidential election of 1928, Hoover easily won the Republican nomination, despite having no previous elected office experience. To date, Hoover is the last cabinet secretary to be directly elected President of the United States, as well as one of only two Presidents (along with William Howard Taft) to have been elected without previous electoral experience or high military rank. America was prosperous and optimistic at the time, leading to a landslide victory for Hoover over Democrat Al Smith.
Hoover, a trained engineer, deeply believed in the Efficiency Movement, which held that government and the economy were riddled with inefficiency and waste, and could be improved by experts who could identify the problems and solve them. When the Wall Street Crash of 1929 struck less than eight months after he took office, Hoover tried to combat the ensuing Great Depression with volunteer efforts, public works projects such as the Hoover Dam, tariffs such as the Smoot-Hawley Tariff, and raising the top tax bracket from 25% to 63% [1] none of which produced economic recovery during his term. The consensus among historians is that Hoover's defeat in the 1932 election was caused primarily by failure to end the downward economic spiral. As a result of these factors, Hoover is ranked poorly among former US Presidents.
