Paul Allen Was So Much More Than Microsoft's Co-Founder

Personal computers, conservation, pro football, rock n' roll and rocket ships: Paul G. Allen couldn't have asked for a better way to spend, invest and donate the billions he reaped from co-founding Microsoft with childhood friend Bill Gates. Allen used the fortune he made from Microsoft -- whose Windows operating system is found on most of the world's desktop computers -- to invest in other ambitions, from tackling climate change and advancing brain research to finding innovative solutions to solve some of the world's biggest challenges. "If it has the potential to do good, then we should do it," Gates quoted his friend as saying. Allen died Monday in Seattle from complications of non-Hodgkin's lymphoma, according to his company Vulcan Inc. Just two weeks ago, Allen, who owned the NFL's Seattle Seahawks and the NBA's Portland Trail Blazers, had announced that the same cancer he had in 2009 had returned.
