Paul Allen, the philanthropist and co-founder of Microsoft, died Monday in Seattle from complications of non-Hodgkin's lymphoma. He was 65.
In a statement, his sister, Jody, said Allen was "a remarkable individual on every level." Microsoft CEO Satya Nadella said Allen "created magical products, experiences, and institutions, and in doing so, he changed the world." Allen founded Microsoft in 1975 with Bill Gates, and after leaving the company, he founded Vulcan Inc., which oversaw his philanthropic and business endeavors.
One of the world's wealthiest people, Allen's net worth was estimated at more than $20 billion. He owned the Portland Trail Blazers and Seattle Seahawks, plus had a stake in the Seattle Sounders soccer team. Allen was diagnosed nine years ago with non-Hodgkin's lymphoma, and announced earlier this month he had started treatment for it again. Catherine Garcia
