Steve Ballmer (born March 28, 1956) is the President and CEO of Microsoft Corporation.
Ballmer is the first person ever to become a (US-dollar) billionaire based on stock options received as an employee in a corporation of which neither he nor a relative was not the founder.
He is a graduate of Harvard College.
Due to his wild exuberance, particularly in a widely circulated video clip in which he screams and dances onstage at a conference, he is know as 'Monkey Boy'.
