Thomas Emley Young (1844 - 1 September 1933) was the president of the Institute of Actuaries, London, in 1898.
Thomas Emley Young was born in 1844 in Newcastle-upon-Tyne, England. He married Harriet Maria (nee Rayner) in 1871 in Islington, London. They had five children between 1874 and 1880: Edith, Arthur, Ernest, Sidney, and Hilda.
He wrote a book entitled "Centenarians" (published in 1899; revised version issued 1905). His work included the first supercentenarian case validation, that of Margaret Ann Neve (validated in 1898 at 106 but reached age 110 in 1902). Thomas Emley Young was also the first person to create a validated list of centenarians using the "age in years and days" ranking format, in 1898.
