Microsoft co-founder Paul Allen has died from cancer

Paul Allen, the co-founder of Microsoft, passed away Monday. He was 65.

His death was confirmed by a statement from his company, Vulcan Inc, reports CNBC, and was the result of complications stemming from non-Hodgkin's lymphoma.

Allen's sister, Jody Allen, released the following statement: 

Microsoft CEO Satya Nadella issued a statement this afternoon, lauding Allen's accomplishments and noting that "[our] hearts are with Paul's family and loved ones."

Allen founded Microsoft with Bill Gates in 1975. He owned an NBA team, the Portland Trail Blazers, and the NFL’s Seattle Seahawks.

Allen's 2011 memoir, Idea Man, recounted the early days at Microsoft and, according to Allen, the working relationship he had with Gates. He elaborated on that relationship in an interview with the Guardian.

"During the founding first eight years my ideas were definitely key to the company," Allen is quoted as explaining. "When it came to selling and marketing and staffing and all those kinds of things, [Gates] was much more excited on the business side, so we became very complementary."

This story has been updated to include mention of Allen's memoir.
