Timothy Otis Howe (February 24, 1816 – March 25, 1883) was a member of the United States Senate for three terms, representing the state of Wisconsin from March 4, 1861, to March 3, 1879. He also served as U.S. Postmaster General under President Chester A. Arthur from 1881 until his death in 1883. Earlier in his career, he was a justice of the Wisconsin Supreme Court.^[1]

Howe was born in Livermore, Maine (then, part of the commonwealth of Massachusetts), to Timothy Howe and Betsey Howard, attended Readfield Seminary now Kents Hill School, in Readfield, Maine, and studied law with local judges.^[2] In 1839, Howe was admitted to the Maine Bar and began practicing law in Readfield. In 1845, he was elected to the Maine House of Representatives.^[3] Shortly thereafter, Howe moved to Green Bay, Wisconsin, and opened a law office. He was an ardent Whig and ran an unsuccessful campaign for U.S. Congress in 1848.

Howe married Linda Ann Haines and together the couple had 2 children, Mary E. Howe and Frank K. Howe.

Howe was elected circuit judge in Wisconsin and served in that position from 1851 to 1855. As a circuit judge, he also served as a justice of the Wisconsin Supreme Court until a separate Supreme Court was organized in 1853.

In 1857, Howe ran unsuccessfully for the U.S. Senate.^[4] In 1861, Howe ran again and won election to the Senate,^[4] serving during the American Civil War and Reconstruction. During his time in the Senate, he was an abolitionist and supporter of the Fifteenth Amendment. Howe argued against the claims of contemporary Democrats that blacks were inherently racially inferior, and remarked that their claim that abolition would cause a war of racial extermination was "a libel upon humanity, black or white."^[5] During this time he was considered one of the "Radical Republicans" due to his support for racial equality and his opposition to discrimination.^[6]

1865 Congressional Hearings chaired by Senator Doolittle looked into Sioux Complaints from the Yankton and Dakota tribes.^[7] The Senator found: "Many agents, teachers, and employees of the government, are inefficient, faithless, and even guilty of peculations are fraudulent practices upon the government and upon the Indians." Yankton Chief Medicine Cow testified that Government Agents were the cause of the Minnesota problems. What those agents did in Minnesota was a harbinger of the history coming for the other tribes of the plains.

While in the Senate, President Ulysses S. Grant offered Howe the position of Chief Justice of the U.S. Supreme Court. However, Howe declined the offer because he feared his successor to the Senate would be a Democrat. Howe lost his senate seat in 1879 to fellow Republican Matthew H. Carpenter. In 1881, he was appointed United States Postmaster General by President Chester A. Arthur, a position he held until his death in Kenosha, Wisconsin, on March 25, 1883.^[4]
