Paul Allen, who co-founded Microsoft with Bill Gates, has passed away after a two-week battle with relapsed non-Hodgkin’s lymphoma.
Allen announced in early October that the cancer of the lymphatic system, for which he was treated in 2009, had returned. He wrote that the doctors were optimistic and that he intended to fight the disease.
He passed away in Seattle on Monday afternoon, his investment firm Vulcan confirmed in a statement.
“My brother was a remarkable individual on every level,” his sister Jody Allen said in a statement on behalf of his family. “He was a much loved brother and uncle, and an exceptional friend.”
