Paul Allen, who co-founded Microsoft with Bill Gates in 1975, has died as a result of complications from non-Hodgkin's lymphoma. 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 Allen, said in a statement.
