John Walker (Missouri politician)

John Walker (October 15, 1770 – May 26, 1838) was a U.S. politician from Missouri.

John Walker was born in Brunswick County, Virginia. He later moved to Kentucky, and eventually settled in Howard County, Missouri in 1818. His wife Sarah Caffery, whom he married in 1800, was a niece of Rachel Jackson, the wife of Andrew Jackson. Walker was a member of a prominent Kentucky political family. He was the brother of Kentucky senator George Walker and Congressman David Walker and the uncle of James D. Walker, David S. Walker and Richard K. Call. His son John George Walker served as a Confederate general during the Civil War.

A decade after moving to Missouri, John Walker was elected to the Missouri State Senate. He was elected as State Treasurer of Missouri in 1833. According to legend, he never kept the Treasurer's Office locked or bolted, but secured government funds in an iron-bound oaken chest, and reportedly slept on top of the chest at night. Following his death in office, $400 in government funds were reported missing. Nonetheless, he was exonerated by the Missouri General Assembly on charges of misappropriation of funds. Several years later, the money was discovered in between the metal lining and walls of the chest.
