9 Jan. 1828–16 May 1888
In 1861 Smith was elected by Johnston County as a Union man to the secession convention. He opposed secession and voted against it. In 1864 he won a seat in the North Carolina House of Commons. When Governor William Woods Holden called the constitutional convention of 1865, Smith was again elected to serve his county. With the advent of congressional Reconstruction, he joined the Republican party. In 1868 Holden appointed him president of the North Carolina Railroad, headquartered in Alamance County.
As railroad president, Smith supported efforts to expand the company's service to the state by advocating the merger of several small railroad lines into one major company. The General Assembly opposed these efforts. When the state's Democrats met in convention in 1868, Smith refused to give reduced rail rates to them but did grant a 50 percent reduction for the Republicans that year. The North Carolina Railroad was again used for political purposes when the legislature of 1869 investigated charges of fraud in the state government. Governor Holden and Smith spirited a key witness, George W. Swepson, out of town on a special midnight train to prevent his appearance before the special inquiry committee. In 1871 the railroad was leased to the Richmond and Danville Railroad.
While living in Alamance County, Smith was elected to the state senate in 1870, but the election was contested. The General Assembly decided to allow Smith to be seated but called for an investigation. It later declared his seat vacant because Alamance County was considered in a state of insurrection due to Governor Holden's order for state troops to occupy the county after the murder of Wyatt Outlaw, a black man, by members of the Ku Klux Klan. In a new election, a Democrat was voted into office.
In March 1870 Smith purchased the Raleigh Standard from M. S. Littlefield. The paper was the state's major Republican organ, with editorial leadership in the hands of Joseph W. Holden, the governor's son and former proprietor of the Standard. The following September Smith sold the paper, reportedly saying, "I stopped printing the Standard because you can't print a paper for a party that can't read."
In 1872 he was elected as a Republican to represent the Fourth District in the U.S. House of Representatives, where he served on the Committee of Public Expenditures. Smith declined to run for reelection in 1874. He was appointed U.S. court receiver of the Western North Carolina Railroad Company, of which he later became president. The Republican party nominated him for lieutenant governor in 1876, but he was defeated along with Judge Thomas Settle, the gubernatorial candidate that year.
In 1876 Smith retired to his farm at Princeton in Johnston County. A lifelong Methodist, he died of stomach cancer at the home of his son-in-law, Captain William H. Green, in Richmond, Va. He was buried in Hollywood Cemetery, Richmond. His wife, who died in 1892, was interred in Selma, Johnston County.
