Microsoft co-founder Paul Allen has died aged 65 from complications of non-Hodgkin's lymphoma. He was previously treated for disease in 2009.
His Microsoft co-founder Bill Gates said: "I am heartbroken by the passing of one of my oldest and dearest friends... Personal computing would not have existed without him." He added: "From our early days together at Lakeside School, through our partnership in the creation of Microsoft, to some of our joint philanthropic projects over the years, Paul was a true partner and dear friend."
Allen and Bill
Allen’s sister Jody described the businessman as a "remarkable individual on every level". "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," a family statement said. Mr Allen didn't always have a great relationship with his co-founder, Bill Gates. But they shared an awful lot in common, first as children learning programming, and then as adults donating billions to philanthropic efforts. He is estimated to have donated more than $2bn to philanthropy throughout his life and decided to give the majority of his fortune to charitable causes after his death. He owned both the Portland Trail Blazers basketball team and Seattle Seahawks NFL team, who won the US Superbowl in 2013.
