Moses S. Gibson (1816 - December 6, 1904) was an American banker from Hudson, Wisconsin, who served as a Representative in the last two sessions of the Legislative Assembly of the Wisconsin Territory,[1] as a member of the First Wisconsin Constitutional Convention, and was elected to a term in 1859 as a member of the Wisconsin State Assembly after statehood, an election successfully contested by Marcus W. McCracken.[2] Gibson's political party affiliation is unknown.[3]
Gibson was born in 1816 in Livingston County, New York.[4] He settled in Fond Du Lac, Wisconsin, in 1844. He was elected as a member of the First Wisconsin Constitutional Convention in 1846 and elected to the Legislative Assembly of the Wisconsin Territory in 1847 and 1848. In 1849, he moved to Hudson, Wisconsin, where he was appointed receiver of public moneys. He married Carrie F. Gilman in 1856. In 1859, he was elected to a term in the Wisconsin State Assembly. During the Civil War, he was appointed a paymaster and assigned to Missouri, and also became a major.[5] In 1878, he was appointed a position in the sixth auditor's office of the treasury in the post office department. He died on December 6, 1904, in Washington, D. C.,[6] and was buried in Arlington National Cemetery.
In the State Assembly, Gibson was to represent the district which included the sparsely-populated Ashland, Burnett, Douglas, La Pointe, Polk, and St. Croix counties to succeed Republican James B. Gray. McCracken in turn was succeeded by Asaph Whittlesey, also a Republican.
