Who is Neil deGrasse Tyson

So, who is Neil deGrasse Tyson https://en.wikipedia.org/wiki/Neil_deGrasse_Tyson and why is he so popular?  I know what his credentials are.  l love listening to his explanations of science, and I love the entertainment factor he brings to science.  The critics would say he cheapens science by his entertainment factor.  I disagree. I think his ebullient character and media persona serve as wonderful ambassadors to awaken an interest in science in children and adults.
