WALSH, Michael, politician, born in Youghal, Ireland, 7 March, 1810; died in New York city, 17 March, 1859. He went to Baltimore in his youth, received a good education, and became a lithographer. Removing to New York, he entered the assembly in 1839, and continued for many years to be a leader of the Democratic party. He established in 1840 "The Knickerbocker," which was stopped after two years' existence by his conviction and imprisonment for the publication of a libel. On his release he began "The Subterranean," an abusive and scurrilous sheet, that came to an end in a few years. On his release he served in congress, having been elected in 1853-'5 as a Democrat, and was then sent on a confidential mission to England and to Mexico by the government. Mr. Walsh visited the camps of the great contending powers in the Crimea, and was for a time the guest of Carroll Spence, then United States minister in Constantinople, having reached there from Sebastopol penniless and without suitable clothing, He had great talents, independence, and honesty, and was a keen satirist, and his letters from abroad were unrivalled in their vein. He was found dead in the area of a house in New York city. He published his "Speeches, Poems, and other Writings" (New York, 1843).
