In the 1950s, the United States FBI began to maintain a public list of the people it regarded as the Ten Most Wanted Fugitives.
In late 1949 the FBI helped publish an article about the "toughest guys" the Bureau was after, who remained fugitives from justice.
The positive publicity from the story resulted in the birth of the FBI's "Ten Most Wanted Fugitives" list on March 14, 1950.
Organized crime networks and families in the United States also became targets, including those headed by Sam Giancana and John Gotti.
For convenient reference, the wanted fugitive's sequence number and date of entry on the FBI list appear below, whenever possible.
