Paul Allen was Bill Gates' oldest friend and first business partner. They met in 7th grade and bonded over their shared passion for computers. Allen foresaw that computers would change the world and predicted the rise of personal computers. This insight inspired Gates and led to the founding of Microsoft. Without Allen's encouragement and partnership, Microsoft likely would not have happened. Gates remembers Allen as a passionate man devoted to his family and friends as well as a brilliant and philanthropic visionary.
