Neil deGrasse Tyson
Tyson didn't get his celebrity status from his looks, style, acting, or sports prowess. He got it from being the smartest person in the room in pretty much every room he goes into. Tyson has been commended for getting children, specifically underprivileged children of color, interested in sciences and mathematics. But, even though his influence is of utmost importance, he too can become subject to negative emotions.
Man for Hire
Tyson charges clubs and universities up to $85,000 for a single appearance. Lots of venues are happy to pay that price so he can educate the masses on his vast and unique intellect, but others think that this number is too high. Either way, he's making his money where he can.
