Neil deGrasse Tyson is an American astrophysicist and, since 1996, the Frederick P. Rose Director of the Hayden Planetarium at the American Museum of Natural History.
Tyson has written a number of popular books on astronomy. In 1995, he began to write the “Universe” column for “Natural History” magazine. In 2004, he hosted the four-part “Origins” miniseries of PBS’s “Nova,” and co-authored, with Donald Goldsmith (renowned California astronomer and science writer/professor) the companion volume for this series, “Origins: Fourteen Billion Years Of Cosmic Evolution.”
In 2001, President George W. Bush appointed Tyson to serve on the Commission on the Future of the United States Aerospace Industry and in 2004 to serve on the President’s Commission on Implementation of United States Space Exploration Policy, the latter better known as the “Moon, Mars and Beyond” commission. He was soon afterward awarded the NASA Distinguished Public Service Medal, the highest civilian honor bestowed by NASA.
