Thomas L. Hamer

Thomas Lyon Hamer (July 1800 – December 2, 1846) was a Democratic congressman and soldier in the United States.

Hamer was born in July 1800 in Northumberland County, Pennsylvania. He was a school teacher before being admitted to the bar in 1821. He was an Ohio Presidential elector in 1828 for Andrew Jackson.

He practiced law in Georgetown, Ohio and was elected to the Ohio House of Representatives in 1828, which body unanimously chose him as their Speaker in December 1829. As Speaker, he sought to maintain independence from party politics; although Jackson's supporters controlled a slight advantage over John Quincy Adams' supporters, he appointed Adams men as a majority in seven of the fifteen standing committees. When the Jackson caucus proposed enforcing party discipline during judicial elections, Hamer fought the proposal fiercely; envisioning a choice between the party candidate and the candidate he believed best qualified, he denounced a vote for the party candidate as perjury of his oath of office. These statements won him criticism from party stalwarts who deemed him unfaithful to the interests of his party.

When the Mexican–American War broke out Hamer volunteered as a private in the Ohio Volunteers, and was quickly commissioned as a major in June 1846. Popular and well respected, Hamer was appointed a brigadier general of volunteers on July 1, 1846. He was placed in command of the 1st Brigade of William O. Butler's Volunteer Division of the Army of Occupation. He led his brigade with distinction into the fighting at the battle of Monterrey. When General Butler fell wounded, Hamer assumed command of the division. When Mexican General Pedro de Ampudia requested to discuss surrender terms, it was Hamer who delivered the message to General Taylor. While still serving in the army he was elected to another term in Congress but died unexpectedly while stationed with the army at Monterrey on December 2, 1846. Upon Hamer's death, General Zachary Taylor exclaimed "I have lost the balance wheel of my volunteer army" and Lt. Ulysses S. Grant also lamented that the "U.S. has lost a future president." Grant later described him as "one of the ablest men Ohio ever produced."

He was buried in his hometown of Georgetown, a few miles from his namesake village of Hamersville. Also named in his honor is Hamer Township in neighboring Highland County, Ohio.
