Herbert Clark Hoover (1874-1964), the 31st President of the United States, was the first president elected out of a business career.  He had made a fortune as a mining engineer, and then, at the outbreak of World War I, became the food administrator of the United States.  From there he accepted a post on President Harding's cabinet, followed by the presidential nomination by the Republican party.  In his Inaugural Address, March 4, 1929, President Herbert Clark Hoover entreated:

"I ask the help of Almighty God in this service."  - March 4, 1929, in his Inaugural Address.  Benjamin Weiss, God in American History: A Documentation of America's Religious Heritage (Grand Rapids, MI: Zondervan, 1966), p. 132.  Willard Cantelon, Money Master of the World (Plainfield, NJ: Logos International, 1976), p. 121.

In The Challenge of Liberty, 1934, Herbert Clark Hoover declared:

"While I can make no claim for having introduced the term, 'rugged individualism,' I should be proud to have invented it.  It has been used by American leaders for over a half-century in eulogy of those God-fearing men and women of honesty whose stamina and character and fearless assertion of rights led them to make their own way of life."  - 1934, in The Challenge of Liberty, ch. 5.  John Bartlett, Bartlett's Familiar Quotations (Boston: Little, Brown and Company, 1855, 1980), p. 750.

Herbert Hoover, in 1943, issued a joint statement along with Mrs. Calvin Coolidge, Mrs. Theodore Roosevelt, Mrs. William H. Taft, Mrs. Benjamin Harrison, Mrs. Grover Cleveland, Alfred Smith, Alfred Landon, James M. Cox, and John W. Davis:

"Menaced by collectivist trends, we must seek revival of our strength in the spiritual foundations which are the bedrock of our republic.  Democracy is the outgrowth of the religious conviction of the sacredness of every human life.  On the religious side, its highest embodiment is The Bible; on the political side, the Constitution."  - "Our Christian Heritage," Letter from Plymouth Rock (Marlborough, NH: The Plymouth Rock Foundation), p. 7.

President Herbert Hoover stated:

"The whole inspiration of our civilization springs from the teachings of Christ and the lessons of the prophets.  To read the Bible for those fundamentals is a necessity of American life."  - Charles E. Jones, The Books You Read (Harrisburg, PA: Executive Books, 1985), p. 116.
