J. Edgar Hoover (born January 1, 1895 – died May 2, 1972) was the first Director of the Federal Bureau of Investigation (FBI) of the United States, serving from its founding in 1935 until his death in 1972.
Born in Washington, D.C., Hoover joined the Department of Justice in 1917 and quickly rose through the ranks. In 1924, he became director of the Bureau of Investigation, which later evolved into the FBI. Hoover played a pivotal role in transforming the bureau into a modern and powerful federal law enforcement agency.
Under Hoover's leadership, the FBI pioneered forensic techniques, centralized criminal databases, and became a central force in national security. He was instrumental in combating gangsters during the Prohibition era and in counter-espionage during World War II and the Cold War.
Despite his achievements, Hoover's legacy is controversial. He amassed secret files on public figures, employed surveillance against civil rights leaders like Martin Luther King Jr., and was accused of abusing his authority for political leverage.
