Paul Allen, who co-founded Microsoft with Bill Gates, dies of cancer at 65

Microsoft said Allen's 'contributions to our company, our industry and to our community are indispensable'

Billionaire Paul Allen , who founded US software giant Microsoft with Bill Gates in the 1970s, died Monday after his latest battle with cancer. He was 65.

"My brother was a remarkable individual on every level. While most knew Paul Allen as a technologist and philanthropist, for us he was a much loved brother and uncle, and an exceptional friend," Allen's sister Jody said in a statement.

"Paul's family and friends were blessed to experience his wit, warmth, his generosity and deep concern... At this time of loss and grief for us -- and so many others -- we are profoundly grateful for the care and concern he demonstrated every day."

Allen died just two weeks after publicly revealing that the non-Hodgkin's lymphoma he fought into remission nine years ago had returned. The incurable cancer affects white blood cells.

Allen managed his business and charitable endeavours at Vulcan Inc.

He was also active with the Allen Institutes of scientific research and owned professional US sports teams the Seattle Seahawks and Portland Trail Blazers. He was part owner of the Major League Soccer team the Seattle Sounders. Read More
