Tyson was born as the second of three children in the borough of Manhattan in New York City, but was raised in the Bronx. His mother, Sunchita Feliciano Tyson, was a gerontologist and his father, Cyril deGrasse Tyson, was a sociologist, human resource commissioner for the New York City mayor, John Lindsay, and was the first Director of HARYOU. Tyson attended the Bronx High School of Science (1972–1976, astrophysics emphasis) where he was captain of the wrestling team and was editor-in-chief of the school's Physical Science Journal. Tyson had an abiding interest in astronomy from the age of eleven, following his visit to the Hayden Planetarium at age nine. Tyson recalls 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." He obsessively studied astronomy in his teens, and eventually even gained some fame in the astronomy community by giving lectures on the subject at the age of fifteen.
