Genarians is a website dedicated to listing the world's oldest people:
This website highlights living people in their 90's (nonagenarians) and 100's (centenarians) who were noted in some field during their lifetimes, i.e., the arts, sports, science, politics, business, etc., and then grew old. While some of the 762 names may be familiar to you – Walter Cronkite or Kirk Douglas, for instance – most probably won't be. Please take a moment to look through the pages and discover some of the lesser known, but equally interesting entries such as Leila Denmark (1898), Kazuo Ohno (1906), and Frances Oldham Kelsey (1914).
