Neil deGrasse Tyson grew up in the Castle Hill neighborhood of the Bronx and then in Riverdale. From kindergarten throughout high school, Tyson attended public schools in the Bronx: PS 36 Unionport, PS 81 Robert J. Christen, the Riverdale Kingsbridge Academy (MS 141), and graduated from The Bronx High School of Science in 1976 where he was captain of the wrestling team and editor-in-chief of the Physical Science Journal. His interest in astronomy began at the age of nine after visiting the sky theater of the Hayden Planetarium. He recalled that "so strong was that imprint [of the night sky] that I'm certain that I had no choice in the matter, that in fact, the universe called me." During high school, Tyson attended astronomy courses offered by the Hayden Planetarium, which he called "the most formative period" of his life. He credited Mark Chartrand III, director of the planetarium at the time, as his "first intellectual role model" and his enthusiastic teaching style mixed with humor inspired Tyson to communicate the universe to others the way he did.
