New York, December 18 - Italian-born Dina Manfredini held the title of world's oldest woman for just two weeks before dying in a nursing home in Iowa at age 115. Dina Guerri was born in Pievepelago, in Italy's central Emilia Romagna region, on April 4, 1897 and moved to the United States in 1920 with her husband Riccardo Manfredini. Dina Manfredini worked in a munitions factory during the Second World War and later, as a cleaner, an occupation she continued until she was 90. The title of world's oldest person now goes to Jiroemon Kimura a Japanese man 15 days younger than Manfredini, who died Monday. According to officials at Guinness World Records, Manfredini - who had four children - is the only verified Italian to reach age 115 in documented history.
