約翰?斯珀林

??? 據報道約翰?斯珀林擁有12億美元的凈資產，他的財富來自阿波羅集團（Apollo Group）的首次公開募股，而該集團則擁有盈利性的教育機構鳳凰城大學（University of Phoenix）。91歲的斯珀林此后組建了科學家團隊，旨在減輕人類的病痛和對死亡的恐懼，使用一切手段加強人體生物機能，包括治療性克隆、干細胞醫學和基因工程。他還資助了克洛諾斯長壽研究所（Kronos Longevity Research Institute），后者主要從事年齡相關疾病的臨床研究。

??? John Sperling, who has a reported net worth of $1.2 billion, made his fortune after the initial public offering of the Apollo Group (APOL), which owns the for-profit University of Phoenix. Sperling, 91, has since assembled a team of scientists who aim to alleviate human suffering and fear of death -- using everything from therapeutic cloning, stem cell medicine and genetic engineering to enhance human biology. He also funded the Kronos Longevity Research Institute, which does clinical research on age-related diseases.
