Federal Bureau of Investigation

In February 1992, the FBI established its Criminal Justice Information Services (CJIS) Division in Clarksburg, West Virginia. CJIS became the FBI’s largest division, consolidating key data services including fingerprint identification, criminal history databases, and encrypted communications support, further enhancing nationwide law enforcement information infrastructure.

On September 30, 1973, the new FBI headquarters in Washington, D.C., named the J. Edgar Hoover Building, was formally dedicated. The Bureau officially relocated into this purpose‑built facility, symbolizing its growth into a modern, centralized federal law enforcement agency with a striking physical presence in the nation’s capital.

On May 2, 1972, J. Edgar Hoover died in his sleep in Washington, D.C. after nearly 48 years leading the Bureau of Investigation and the FBI. His death marked the end of an era defined by both the Bureau’s transformation into a premier investigative agency and enduring controversies over surveillance and abuses of power.

On October 15, 1970, Congress enacted the Organized Crime Control Act, introducing the Racketeer Influenced and Corrupt Organizations Act (RICO). This provided the FBI powerful legal tools to dismantle organized crime networks by prosecuting individuals for broader patterns of racketeering and conspiracy, dramatically enhancing its ability to tackle criminal enterprises.

On January 27, 1967 (note: although in timeline category ‘And Justice for All, 1954‑1971’, NCIC launched in 1967), the FBI launched the National Crime Information Center (NCIC), an electronic database system providing nationwide law enforcement access to criminal records, fingerprints, and other vital data in real time from squad cars and stations. NCIC revolutionized information sharing and improved rapid investigative responses across jurisdictions.

On June 24, 1940, at President Franklin D. Roosevelt’s request, the FBI established the Special Intelligence Service (SIS) to counter Axis espionage and sabotage in the Western Hemisphere. Agents were deployed throughout Latin America to collect intelligence, detain enemy agents, and protect U.S. interests abroad during World War II. The SIS laid the groundwork for the FBI’s subsequent international liaison activities.

On July 1, 1935, the Bureau of Investigation officially adopted its modern name, the Federal Bureau of Investigation (FBI). This change reflected its evolution into an independent service within the Department of Justice with broader responsibilities in both law enforcement and national security.

On May 10, 1924, Attorney General Harlan Fiske Stone appointed 29‑year‑old J. Edgar Hoover as Acting Director of the Bureau of Investigation. By the end of the year, Hoover was formally named Director. Under his leadership, the Bureau underwent professional reforms including merit‑based hiring, introduction of background checks, and formation of a centralized fingerprint identification system.

On October 28, 1919, Congress passed the National Motor Vehicle Theft Act, also known as the Dyer Act, granting the Bureau of Investigation the authority to investigate interstate motor vehicle theft. This expanded the Bureau’s jurisdiction significantly, enabling it to pursue criminals crossing state lines and enhancing its role in enforcing federal law.

On July 26, 1908, Attorney General Charles J. Bonaparte appointed a small group of special agents to serve as an investigative force within the Department of Justice. This marked the official origin of what would later become the FBI, providing the U.S. government with its first permanent federal investigative capability. This foundational moment laid the groundwork for a centralized agency dedicated to investigating federal crimes, formalizing responsibilities that had previously fallen to disparate bodies or temporary hires.
