Josiah McNair Anderson was an American politician and a member of the United States House of Representatives for Tennessee's 3rd congressional district. He was born near Pikeville, Tennessee in Bledsoe County on November 29, 1807. He attended the common schools, studied law, was admitted to the bar, and commenced practice in Jasper, Tennessee.
From 1833 to 1837, he was a member of the Tennessee House of Representatives, serving as speaker. He was a member of the Tennessee Senate from 1843 to 1845, serving as its presiding officer. He was elected as a Whig to the Thirty-first United States Congress, but was not a successful candidate for re-election in 1850 to the Thirty-second Congress. He served from March 4, 1849 to March 3, 1851.
He was a delegate from Tennessee to the peace convention of 1861, held in Washington, D.C., in an effort to devise means to prevent the impending war. He was a colonel in the Tennessee State Militia in 1861. He was killed at Looneys Creek, near the present town of Whitwell, Tennessee in Marion County on November 8 of that year, just after having made a secession speech. He was interred on a farm seven miles southeast of Dunlap, Tennessee in Sequatchie County.
An article in the North Carolina Standard newspaper, dated Wednesday, Nov. 27, 1861, states:
Murder of Hon. Josiah M. Anderson of Tennessee - On the day of election, at or near Dunlap, Sequatchie County, Tennessee, Hon. Josiah M. Anderson was set upon by a band of Lincolnite assassins, and stabbed in the back, causing his instant death. Col. Anderson formerly represented the Knoxville District in the Congress of the United States, and was delegate from Tennessee in the "Peace Congress." His only offence for which he was so basely assassinted, was his defence of the South in conversation.
