John B. Salling (15 May 1856 (claimed 15 May 1846) - 16 March 1959) claimed to be the second-to-last surviving Confederate veteran of the American Civil War, after Walter Williams, although like Williams his claim of being a supercentenarian has been debunked. He was initially validated by Guinness as aged 113 years, 1 day (Guinness had mistakenly placed his birthdate at 15 March 1846 rather than 15 May 1846), but was then downgraded to 112 years, 305 days. When his claimed age was debunked, Guinness withdrew recognition of the case and abolished the "oldest soldier" category but later gave the title to Antonio Todde.
