Paul G. Allen, co-founder of Microsoft, died on Monday afternoon in Seattle from complications of non-Hodgkin’s lymphoma, a statement from his family said. He was 65.
Two weeks ago, Allen had tweeted that the illness, with which he was initially diagnosed in 2009, had returned. "I’ve begun treatment & my doctors are optimistic that I will see a good result. Appreciate the support I’ve received & count on it as I fight this challenge," he wrote.
Allen was the owner of the Seattle Seahawks football team and the Portland Trailblazers basketball team; he was also a part-owner of the Seattle Sounders soccer team. In addition, he founded Seattle's Museum of Pop Culture, and was the founder and chairman of Vulcan Inc., which managed his various business and charity efforts.
Allen and Bill Gates founded Microsoft in 1975. Allen's net worth, which included some 100 million share of Microsoft, was estimated at over $20 billion dollars. He gave over two billion dollars over his lifetime to charitable causes such as environmental conservation, the arts and education.
In a statement, Microsoft Microsoft CEO Satya Nadella said, in part, "Paul Allen's contributions to our company, our industry and to our community are indispensable. As a co-founder of Microsoft, in his own quiet and persistent way, he created magical products, experiences and institutions, and in doing so, he changed the world."
Allen never married and had no children.
