Neil deGrasse Tyson

Neil deGrasse Tyson is an astrophysicist and curator of the American Museum of Natural History's Hayden Planetarium. He became a well-known science personality after being among the group of scientists that re-classified Pluto as a dwarf planet. He ended up citing the Disney character, who was created the same year Pluto was discovered, as being a significant contributor to the public attachment to the planet and the backlash that ensued after the reclassification official.

In 2014, he would guest star on Gravity Falls as the voice of an intelligence enhanced Waddles.
