Alexander Graham Bell (3 March 1847 – 2 August 1922) was Scottish-born scientist and inventor. Better-known for his association with the telephone, Bell's Genealogical Record Office in Washington, D.C. and also in Nova Scotia tracked human longevity (90+). He was one of the first persons involved in the validation of exceptional longevity, and his work concerning this was featured in National Geographic magazine in 1919. He is credited for the validation of Ann Pouder (1807-1917).[1]
