Joseph W. Mansur

Joseph Warren Mansur (December 7, 1808 – February 4, 1892) was an American lawyer, politician, and investor. He represented Lowell, Massachusetts in the Massachusetts House of Representatives in 1837, and in 1852 represented Fitchburg. He served in the Massachusetts Senate representing Middlesex in 1840 and Worcester District in 1854.

Mansur was born in Pembroke, New Hampshire, the son of Aaron Mansur and Rebecca Warren. He studied at Phillips Academy and graduated from Harvard College and Law School in 1831. He later settled in Fitchburg, Massachusetts, where he owned a textile mill. He married Anna Fitzpatrick of Ireland and they had four children.

Mansur also held local office, ran unsuccessfully for US Congress in 1842, and ran unsuccessfully for statewide office on the Democratic ticket in 1860. Mansur's eulogy of Daniel Webster (who died in 1852) won him note.

In the early 1860s Mansur moved to Michigan, and in 1863 owned the Kalamazoo Gazette. He later lived in Sandwich, Ontario and Lennoxville, Quebec, before returning to Massachusetts where he lived in Duxbury and Milton. He died in Hyde Park in February 1892.
