Carl Milton Levin (1934-2021) was an American attorney and politician who served as a U.S. Senator from Michigan from 1979 to 2015, making him Michigan's longest-serving senator. Born on June 28, 1934, in Detroit, Michigan, to a Jewish family, he earned a Bachelor of Arts degree from Columbia University in 1956 and a law degree from Harvard Law School in 1959. After serving in the U.S. Army Signal Corps from 1959 to 1960, he worked as a lawyer in Detroit and held public service roles including with the Michigan Civil Rights Commission (1964–1967) and as chief appellate defender for Detroit (1968–1969). Levin served on the Detroit City Council from 1969 to 1977, focusing on housing, urban renewal, and civil rights. Elected to the Senate in 1978, he was a long-time chair or ranking member of the Senate Armed Services Committee, chairing it from 2001 to 2003 and from 2007 to 2015. He led congressional oversight of Iraq War intelligence and played pivotal roles in defense policy, military operations oversight, and investigations into financial regulations. Levin also chaired the Senate Permanent Subcommittee on Investigations, leading probes into corporate tax avoidance and Wall Street practices. Known for his bipartisan approach, integrity, and diligence, he earned widespread respect across party lines for his resourcefulness, consensus-building, and commitment to ethical governance. His brother, Sander Levin, served as a U.S. Representative from Michigan. After retiring in 2015, Levin co-founded the Levin Center for Oversight and Democracy to promote government accountability. He passed away from lung cancer on July 29, 2021, in Detroit at the age of 87. Throughout his career, Levin left a lasting impact on national security and government oversight policies.
