Neil deGrasse Tyson is an American astrophysicist, cosmologist, author, and science communicator. Born and raised in New York City, Tyson became interested in astronomy at the age of nine after a visit to the Hayden Planetarium. After graduating from the Bronx High School of Science, where he was editor-in-chief of the Physical Science Journal, he completed a bachelor's degree in physics at Harvard University in 1980. After receiving a master's degree in astronomy at the University of Texas at Austin in 1983, he earned his master's (1989) and doctorate (1991) in astrophysics at Columbia University. For the next three years, he was a postdoctoral research associate at Princeton University. In 1994 he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210-million reconstruction project, which was completed in 2000. From 1995 to 2005, Tyson wrote monthly essays in the "Universe" column for Natural History magazine, some of which were published in his book Death by Black Hole (2007). During the same period, he wrote a monthly column in Star Date magazine, answering questions about the universe under the pen name "Merlin". Material from the column appeared in his books Merlin's Tour of the Universe (1998) and Just Visiting This Planet (1998). Tyson served on a 2001 government commission on the future of the U.S. aerospace industry, and on the 2004 Moon, Mars and Beyond commission. He was awarded the NASA Distinguished Public Service Medal in the same year. In 2014, he hosted the television series Cosmos: A Spacetime Odyssey, a successor to Carl Sagan's 1980 series Cosmos: A Personal Voyage. As a science communicator, Tyson regularly appears on television, radio, and various other media outlets.
