Born in Trenton, New Jersey, he was tutored privately in Flushing, Queens, and graduated from the College of New Jersey in 1838. He studied law and was admitted to the bar in 1841 and commenced practice in Trenton. Served as commissioner in bankruptcy. Wall moved to Burlington, New Jersey in 1847, and was elected Mayor of Burlington, New Jersey in 1850; he was nominated for the Democratic nomination for Congress in 1850, but declined. He was an unsuccessful candidate for election in 1854 to the Thirty-fourth United States Congress. Wall supported John C. Breckinridge in the presidential election of 1860, then was involved in the "editorial direction of the New York Daily News, a peace organ that the government suppressed in August 1861." The 12 September 1861 edition of The New York Times reported the arrest of Wall on charges of "secession proclivities". There was a rumor in Trenton that other arrests would be made. He was confined in Fort Lafayette for several weeks. Political prisoner Wall was released with George L. Bowne and Pierce Butler. Released after pledging allegiance to the Union, Wall wrote a letter to the editor stating: "There, if the great principles of constitutional liberty are not a delusion and a snare, and our boasted freedom a sham, may yet be found a place of refuge for liberty against despotism -- the oppressed from the oppressor." Wall, a newspaper editor, was alluding to the presence of Simon Cameron at the bar of the Continental Hotel in Philadelphia. Cameron had ordered his arrest. The New York Times published Wall's letter on the first anniversary of the Pratt Street Riot. Wall was elected by the New Jersey legislature as a Democrat to the United States Senate to fill the vacancy caused by the death of John Renshaw Thomson and served from January 14 to March 3, 1863. He was an unsuccessful candidate for reelection. Wall was a shameless literary plagiarist: entire pages of description of Italy in his 1856 book Foreign Etchings were stolen without attribution from a 1849 book Notes of a two years' residence in Italy by the Irishman Hamilton Geale. Wall resumed the practice of law in Burlington; also engaged in literary pursuits. He moved to Elizabeth, New Jersey in 1869, where he died, aged 52. He was buried in Saint Mary's Episcopal Churchyard in Burlington, New Jersey.
