Guido Calabresi

Yale, in 2006, created the Guido Calabresi Professorship of Law, with Kenji Yoshino serving as the inaugural professor of the endowed chair. Daniel Markovits is the current holder of the chair.

On February 9, 1994, President Bill Clinton nominated Calabresi as a United States Circuit Judge of the United States Court of Appeals for the Second Circuit, he was confirmed by the United States Senate on July 18, received his commission on July 21, and entered duty on September 16, 1994, replacing Thomas Joseph Meskill. President Clinton is a 1973 graduate of the Yale Law School, although he never had Calabresi as a professor. Among Calabresi's group of former students are Supreme Court Justices Samuel Alito, Clarence Thomas and Sonia Sotomayor, former United States Attorney General Michael Mukasey, feminist legal scholar and law professor at the Universities of Michigan and Chicago Catharine MacKinnon, former White House Counsel Gregory Craig, legal scholar Philip Bobbitt, Senator John Danforth, Harvard Law School professor Richard H. Fallon Jr., civil and human rights legal scholar Kenji Yoshino, torts scholar and law professor at the University of Virginia Kenneth Abraham, feminist international attorney Ann Olivarius, and New York University School of Law torts professor Catherine Sharkey. Calabresi, alone among Yale Law School faculty members, supported Thomas's nomination to the Supreme Court.

In 1985, he was awarded the Laetare Medal by the University of Notre Dame, the oldest and most prestigious award for American Catholics.

Calabresi is a member of the Connecticut Bar Association and from 1971 to 1975 served as town selectman for Woodbridge, Connecticut.

Calabresi had been offered a full professorship at the University of Chicago Law School in 1960. However, he joined the faculty of the Yale Law School upon completion of his Supreme Court clerkship, becoming the youngest ever full professor at Yale Law, and was Dean from 1985 to 1994. He now is Sterling Professor Emeritus of Law and Professorial Lecturer in Law at Yale.

Calabresi received his Bachelor of Science degree summa cum laude from Yale College in 1953, majoring in economics — a choice which would have significant connections with his later pursuits. He was then selected as a Rhodes Scholar, studying at Magdalen College, Oxford, which awarded him a Bachelor of Arts degree with First Class Honors in 1955. This was later promoted by seniority to a Master of Arts in 1959. He received his Bachelor of Laws (LL.B.) magna cum laude from Yale Law School in 1958, graduating first in his class, and was also a law review member as Note Editor of the Yale Law Journal from 1957 to 1958. Following graduation from Yale Law, Calabresi served as a law clerk for United States Supreme Court associate justice Hugo Black from 1958 to 1959. Additionally, he is a member of Phi Beta Kappa and the Order of the Coif.

Calabresi married Anne Gordon Audubon Tyler, a social anthropologist, freelance writer, social activist, philanthropist and arts patron. Both received their primary education at the Foote School in New Haven, graduating in 1946 and 1948, respectively. Calabresi would continue on to receive his secondary education from Hopkins School, graduating in 1949. They reside in Woodbridge, Connecticut, and have three children. Anne Gordon Audubon Calabresi (Anne Calabresi Oldshue), a psychiatrist, graduated cum laude from Yale, attended medical school at Case Western Reserve University and completed residency at Harvard. Massimo Franklin Tyler ("M.F.T.") Calabresi, a journalist with Time magazine, also graduated from Yale. Bianca Finzi-Contini Calabresi attended Yale as well, graduating summa cum laude, and has a Ph.D. in Renaissance literature from Columbia. Calabresi's nephew, Steven G. Calabresi, is a Constitutional Law professor at Northwestern University and a co-founder of the Federalist Society.

Guido Calabresi (born October 18, 1932) is an Italian-born American legal scholar and Senior United States circuit judge of the United States Court of Appeals for the Second Circuit. He is a former Dean of Yale Law School, where he has been a professor since 1959. Calabresi is considered, along with Ronald Coase and Richard Posner, a founder of the field of law and economics.

Calabresi is the son of the late cardiologist Massimo Calabresi and European literature scholar Bianca Maria Finzi-Contini Calabresi (1902–1982). Calabresi's parents, active in the resistance against Italian fascism, eventually fled Milan for New Haven, Connecticut, immigrating to the United States in September 1939. The family became naturalized American citizens in 1948. Guido's older brother Paul Calabresi (1930–2003) was a prominent medical and pharmacological researcher of cancer and oncology. Calabresi's mother descends from an Italian-Jewish family. He describes himself as a "practicing Catholic" who believes in God.
