Sonia Sotomayor Facts: From the Bronx to the Bench

Sonia Sotomayor is an Associate Justice of the U.S. Supreme Court, the first Hispanic person and the third woman to serve on the Court. Among the core facts about Sonia Sotomayor: she was born June 25, 1954, in the Bronx; President Barack Obama nominated her on May 26, 2009; and the Senate confirmed her on August 6, 2009, by a vote of 68 to 31.¹ She was sworn in two days later, on August 8, 2009, and remains on the bench at 71.²

Growing Up in the Bronx

Sotomayor was raised in a South Bronx housing project, the daughter of Puerto Rican parents. Her father, who had a third-grade education and spoke little English, worked in a factory. Her mother was a nurse. Her father died when Sotomayor was nine, and her mother raised Sotomayor and her younger brother Juan largely on her own.

At roughly seven and a half, Sotomayor was diagnosed with Type 1 diabetes, a condition she has managed every day since. She has partnered with Breakthrough T1D (formerly JDRF) to raise awareness about the 1.6 million Americans living with the disease.³

Princeton and Yale

Sotomayor graduated summa cum laude from Princeton University in 1976 and received the Moses Taylor Pyne Honor Prize, the highest general distinction Princeton confers on an undergraduate.⁴ She went on to Yale Law School, where she edited the Yale Law Journal and earned her J.D. in 1979.²

Prosecutor and Private Practice

Manhattan District Attorney Robert Morgenthau recruited Sotomayor out of Yale in 1979. She spent five years prosecuting crimes that ranged from robberies to murders during one of New York City’s worst crime waves. She then joined Pavia & Harcourt, a mid-size firm, where she specialized in intellectual property and international commercial litigation.

The Federal Judge Who Ended the Baseball Strike

President George H.W. Bush nominated Sotomayor to the U.S. District Court for the Southern District of New York in 1991, and the Senate confirmed her the following year.⁵⁶⁷

Second Circuit and the Road to the Supreme Court

President Bill Clinton elevated her to the U.S. Court of Appeals for the Second Circuit, where she served from 1998 until her Supreme Court nomination.² More than a decade on the Second Circuit built the appellate record Obama drew on in choosing a replacement for Justice David Souter.

Her confirmation hearings turned in part on a sentence from a 2001 lecture at the University of California, Berkeley: “I would hope that a wise Latina woman with the richness of her experiences would more often than not reach a better conclusion than a white male who hasn’t lived that life.”⁸ Senators pressed her on the line; the full speech addressed how personal background shapes a judge’s perspective.

Signature Opinions on the Supreme Court

Sotomayor is often described as the Court’s foremost defender of Fourth Amendment protections against unreasonable searches and seizures, a reputation she has built in majority opinions, concurrences, and especially dissents.

Utah v. Strieff (2016)

The Court held that evidence found during an unlawful police stop was admissible because the officer discovered an outstanding warrant during the stop. Sotomayor called this a “remarkable proposition” in dissent, arguing it would encourage officers to stop people on a hunch and then exploit the illegal stop to fish for evidence. She wrote at length about the disproportionate impact of such stops on communities of color.⁹

Michigan v. Bryant (2011)

Writing for the majority, Sotomayor held that a dying shooting victim’s identification of his attacker was not “testimonial” because the officers’ primary purpose was to respond to an ongoing emergency rather than to build a prosecution. The ruling drew a line around when the Sixth Amendment’s Confrontation Clause applies.¹⁰

Schuette v. Coalition to Defend Affirmative Action (2014)

Sotomayor dissented at length from the decision upholding a Michigan constitutional amendment banning race-conscious admissions policies. She argued the amendment restructured the political process in a way that disadvantaged minority groups and violated the Equal Protection Clause.¹¹

Other Majority Opinions

She wrote for the Court in Samsung Electronics Co. v. Apple, Inc. (2016), holding that patent infringement damages for a multicomponent product can be based on a single component rather than the entire product; in Collins v. Virginia (2018), ruling that police cannot enter the area around a home without a warrant to search a vehicle parked there; and in Andy Warhol Foundation for Visual Arts, Inc. v. Goldsmith (2023), tightening the fair-use defense in copyright law when a secondary work serves the same commercial purpose as the original.¹²

Books and Public Appearances

Sotomayor’s 2013 memoir, My Beloved World, reached the top of the New York Times bestseller list for hardcover nonfiction. It covers her Bronx childhood, her parents’ struggles, her marriage and divorce, and her path to the federal bench, and it is unusually candid for a sitting justice.

She has also written for younger readers. Just Ask! Be Different, Be Brave, Be You encourages children with disabilities and chronic health conditions to talk openly about their differences. A musical adaptation premiered at The Coterie Theater in Kansas City in January 2025.³ She has appeared on Sesame Street more than once, settling a dispute involving Goldilocks on one occasion and offering career advice to the character Abby on another.
