Born in Canada, near Detroit, on August 21, 1821, Isaac Messmore grew up in Michigan and later studied law as a young man, graduating from the Richmond Law School in Virginia. He went on to live in Louisiana Crosse, Wisconsin, where he practiced law in the 1850s.
In 1861, he served in the Wisconsin State Assembly as a Republican. Later in 1861, he was appointed a Wisconsin Circuit Court judge. However, his appointment to the bench was ruled to have been improperly authorized by the governor, and thus invalid.
After the end of the war, Messmore resettled in Washington, District of Columbia where he was very soon appointed assistant commissioner of the Internal Revenue Bureau.
While in Washington in 1867, he acquired the older Meridian Hill estate, which sat a short distance north of the White House. He then subdivided this tract of land, selling its lots to create a new neighborhood.
In the late 1860s, he next served on the Metropolitan Revenue Board of the City of New York, primarily fighting excise-tax fraud. Messmore subsequently moved to Grand Rapids, Michigan where he purchased and became, in 1881, the editor and publisher of the newspaper The Democrat.
He later relocated to Los Angeles, California about 1888, where he was active in the state Democratic Party there—in 1894 running for, but losing, the position of Representative from the Sixth Congressional District.
Colonel Messmore was noted to have been a defender of the rights of the average citizen against the economic power of the Railroads. Personal information. Isaac first married Editha McKenney in 1848.
