Paul Allen, Bill Gates' co-founder of Microsoft, died on Monday at the age of 65 after suffering from a type of lymphoma.
"Today, our president, our teacher and our friend, whose sixty-six years are very short, recognize the honor of working alongside someone whose life has changed the world," Vulcan's investment company said in a statement.
Allen was diagnosed with leukemia a few years ago, but announced his recovery in 2009.
Allen founded Microsoft with his childhood friend Gates in 1975, but broke the partnership and quit the company in 1983 after suffering cancer.
Allen collected a huge fortune of about $ 20 billion and was one of the wealthiest men in the world.
