Dr. Lewis Heisler Ball (September 21 1861 – October 18 1932) was an American physician and politician from Mill Creek Hundred, New Castle County, Delaware, near Stanton. He was a member of the Republican Party, who served as U.S. Representative from Delaware and two terms as U.S. Senator from Delaware. He was known by his middle name.
Ball was a Regular Republican, and an outspoken opponent of Addicks. As such he was elected State Treasurer of Delaware from 1899 to 1901. He was then elected to the U.S. House of Representatives in 1900. During this term, he served with the Republican majority in the 57th Congress from March 4 1901 until March 3 1903. This was during the administrations of U.S. Presidents William McKinley and Theodore Roosevelt.
In 1899, one of the U.S. Senate seats came open and the Union Republicans in the Delaware General Assembly were committed to electing Addicks. Without the votes to do so, they were able to block the election of anyone else. As a result, one of Delaware's U.S. Senate seats remained vacant for four years, and when the other came open, it too was left vacant due to the deadlock. Finally, in 1903, the matter became national news and too much of an embarrassment to continue. Addicks relented and allowed Ball to be elected to the remaining two years left on the first seat and Addicks' lieutenant, J. Frank Allee was elected to the second seat.
Several years later, in the second popular election of a U.S. Senator in Delaware, Ball was again elected to the U.S. Senate, this time in 1918, defeating incumbent Democratic U.S. Senator Willard Saulsbury, Jr. During this term, Ball served with the Republican majority in the 66th, 67th, and 68th U.S. Congress. In the 66th Congress he was chairman of the Committee on Enrolled Bills and in the 67th and 68th Congress he was a member of the Committee on the District of Columbia. He was also appointed as a member of the rent commission of Washington.
In June 1919 he cast his vote in favor of the Nineteenth Amendment providing for Women's suffrage. Despite this, a year later, when Delaware had the opportunity to be the 36th and decisive state to ratify the amendment and make it law, supporters in the General Assembly failed to get the needed votes and the honor passed to Tennessee.
Ball was never considered an especially effective U.S. Senator in terms of gaining patronage for Delaware. However, he ensured his eventual defeat by becoming a rival of T. Coleman du Pont, the former President of E. I. du Pont de Nemours and Company, and the effective leader of the Republican Party in Delaware. Du Pont had hoped to be the Republican candidate for U.S. President in 1920, but his efforts began to collapse when Ball deserted him after the first ballot at the 1920 Republican National Convention. Then, in 1922, Ball failed to support du Pont as he sought a full term in the U.S. Senate himself. By 1924 du Pont thought he had a score to settle and defeated Ball for their party’s nomination for a full term in 1924.
In all, Ball served two separate terms, the first from March 4 1903 until March 3 1905, during the administration of U.S. President Theodore Roosevelt, and the second from March 4 1919 to March 3 1925, during the administrations of U.S. Presidents Woodrow Wilson, Warren G. Harding and Calvin Coolidge.
