Paul Allen, Microsoft co-founder, billionaire philanthropist and ocean explorer who helped find several lost World War II warships, died on Monday.
Allen, 65, died following a fight with non-Hodgkin’s lymphoma that was first diagnosed in 2009. In an announcement two weeks ago, Allen said his cancer had returned and he had vowed to seek treatment for the disease.
Allen co-founded software giant Microsoft in 1975 with Bill Gates and helped it grow until his departure from the company in 1983.
After Microsoft, the Seattle native was a fixture in the Pacific Northwest as he pursued an array of business and philanthropic causes. Along with mega purchases of yachts and sports teams, he funded research and exploration including robotic sensors and probes to help oceanographers and climate scientists understand the deep ocean.
