U2 frontman Bono was born and raised in Dublin. His real name is Paul Hewson, but as a teen in Ireland he was bestowed with the nickname Bono Vox, a Latin phrase that translates as "Good Voice" and a moniker that has stuck with him both personally and professionally. Besides being a rockstar, Bono is also a venture capitalist and owns an estimated $1 billion worth of shares in Facebook. This technically makes him one of the richest musicians in the world. He's also founded four different charitable organizations and owns a $250 million stake in Forbes Media.
