Jack E. Levin (1925–2018) was a prominent American civil rights attorney born on March 8, 1925, in Philadelphia, Pennsylvania, to Jewish-American parents. He served in the United States Army during World War II, an experience that contributed to his later commitment to justice and equality. After the war, he earned a bachelor's degree in 1947 and a Juris Doctor from Temple University Beasley School of Law in 1950. Levin co-founded the Philadelphia-based law firm Levin, Levin & Gallagher, where he specialized in litigation advancing desegregation and equal rights, notably representing clients in landmark school integration cases during the 1960s, including efforts to dismantle racial segregation in Pennsylvania public schools. Throughout his career, he was recognized for his dedication to civil rights, working on cases that challenged discriminatory practices and promoted access to education for marginalized communities, building a legacy in labor and civil rights law that influenced Philadelphia's legal landscape. Levin was married to Barbara Levin, with whom he had two sons: Mark Levin (born 1957), a well-known conservative radio host, author, and lawyer, and Edward Levin. Widowed after Barbara's passing, he continued his professional work until his death on January 5, 2018, at the age of 92. Despite his son Mark's prominent conservative voice, Jack Levin's career was marked by progressive civil rights advocacy, leaving a lasting impact on American civil rights jurisprudence.
