Antonin Gregory Scalia (help·info) (born March 11, 1936) is an Associate Justice of the Supreme Court of the United States. He was appointed in 1986 by President Ronald Reagan having previously served on the D.C. Circuit and in the Nixon and Ford administrations, and teaching law at the Universities of Virginia and Chicago. He is considered to be a core member of the conservative wing of the court, vigorously advancing textualism in statutory interpretation and originalism in constitutional interpretation.

An only child, Antonin Scalia was born in Trenton, New Jersey; his mother, Catherine Panaro, was born in the United States, while his father, S. Eugene, a professor of Romance languages, had emigrated from Sicily. Five years later, the family moved to the Elmhurst section of Queens, New York, during which time his father worked at Brooklyn College in Flatbush, Brooklyn.

Scalia started his education at Public School 13 in Queens. As a practicing member of the Roman Catholic Church, he attended Xavier High School, a Jesuit school in Manhattan. He graduated first in his class and summa cum laude with an A.B. in History from Georgetown College in 1957. While at Georgetown, he also studied at the University of Fribourg, Switzerland and went on to study law at Harvard Law School, where he was a Notes Editor for the Harvard Law Review. He graduated magna cum laude from Harvard Law in 1960, becoming a Sheldon Fellow of Harvard University the following year. The fellowship allowed him to travel throughout Europe during 1960–1961.
