Bill Gates: Tech Giant and Philanthropist

In 1975, a 19-year-old Bill Gates left Seattle for Albuquerque, New Mexico, and founded Microsoft with his school friend Paul Allen. Over the years that followed he would hold nearly every senior role the company had to offer - chief software architect, chairman, CEO and president - remaining its majority individual shareholder until 2014. This is a detailed account of the driven figure behind the Microsoft revolution, and of the wide-ranging philanthropic work he has pursued in the decade since stepping back from it.
