Paul Allen has passed away at the age of 65 his family announced on Monday.
News of the Microsoft founder’s death comes just two weeks after it was revealed that he was battling non-Hodgkin’s lymphoma for the third time.
It was complications from that cancer which led to his death according to his family.
‘While most knew Paul Allen as a technologist and philanthropist, for us he was a much-loved brother and uncle, and an exceptional friend. Paul’s family and friends were blessed to experience his wit, warmth, his generosity and deep concern,’ said his sister Jody in a statement.
‘For all the demands on his schedule, there was always time for family and friends. 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.’
On the day of his death, Forbes revealed that Allen had donated $95 million in just the past year.
Allen struck gold when he founded Microsoft with Bill Gates, his childhood friend who he convinced to drop out of Harvard to start the company.
