Public enemy is a phrase which was first widely used in the United States in the 1930s to describe individuals whose activities were seen as criminal and extremely damaging to society, though in fact the phrase had been used for centuries to describe pirates and similar outlaws.

The phrase originated in Roman times as Latin: hostis publicus, typically translated into English as the "public enemy".

The modern use of the phrase was first popularized in April 1930 by Frank J. Loesch, then chairman of the Chicago Crime Commission, in an attempt to publicly denounce Al Capone and other organized crime gangsters.

In 1933, Loesch recounted the origin and purpose of the list:

All of those listed were reputed to be gangsters or racketeers and most were rum-running bootleggers. Although all were known to be consistent law breakers (most prominently in regard to the widely broken Eighteenth Amendment to the United States Constitution banning alcohol) none of those named were fugitives or were actively wanted by the law. The list's purpose was clearly to both shame those named and spur the authorities to prosecute them.

Professor Griff is an American rapper and spoken word artist. He is a member of the hip hop group Public Enemy and head of the Security of the First World.

After returning from the army, he started a security service to work the local party circuit, calling it Unity Force. At the time, Carlton Ridenhour (a.k.a. Chuck D) was part of the Spectrum City DJ-for-hire service led by Hank Shocklee, and Spectrum and Unity Force frequently worked side-by-side at local events. When Public Enemy was formed and signed to Def Jam, Ridenhour invited Griffin to be a sideman. Unity Force was renamed "The Security of the First World", or S1W for short. The S1W's were brought along, and became a curious combination of bodyguards/dancers for the band. Their stage routines were a loose combination of martial arts, military drill and "step show" dances lifted from black college fraternities.

His role was also that of road manager and "Minister of Information", the intellectual public face of the band for interviews et cetera, as Flavor Flav was the "fun" one. He was rarely MC'ing, except between songs. Professor Griff has started to emerge on the conspiracy theory scene, typically New World Order conspiracy theory. He is known for linking these allegations to past and present celebrities.

Carlton Douglas Ridenhour (born August 1, 1960), better known by his stage name, Chuck D, is an American rapper, author, and producer. He helped create politically and socially conscious rap music in the mid-1980s as the leader of the rap group Public Enemy.

Ridenhour was born in Queens, New York. After graduating from Roosevelt Junior-Senior High School, he went to Adelphi University on Long Island to study graphic design. He is the son of Lorenzo Ridenhour.

Upon hearing Ridenhour's demo track "Public Enemy Number One", fledgling producer/upcoming music-mogul Rick Rubin insisted on signing him to his Def Jam label.

Their major label albums were: Yo! Bum Rush the Show (1987), It Takes a Nation of Millions to Hold Us Back (1988), Fear of a Black Planet (1990), Apocalypse 91... The Enemy Strikes Black (1991), Greatest Misses (1992), and Muse Sick-n-Hour Mess Age (1994). They also released a full length album soundtrack for the film He Got Game in 1998. Ridenhour also contributed (as Chuck D) to several episodes of the PBS documentary series The Blues. He has appeared as a featured artist on many other songs and albums, having collaborated with artists such as Janet Jackson, Kool Moe Dee, The Dope Poet Society, Run-DMC, Ice Cube, Rage Against The Machine, Anthrax, John Mellencamp and many others. In 1990, he appeared on "Kool Thing", a song by the alternative rock band Sonic Youth. In 1993, he executive produced Got 'Em Running Scared, an album by Ichiban Records group Chief Groovy Loo and the Chosen Tribe.

Ali Newman (born Jason Newman in 1978), better known by the stage name Brother Ali, is an American hip hop artist signed to Rhymesayers Entertainment.

Brother Ali was born in Madison, Wisconsin, and spent his early childhood moving from city to city in the Midwest (mostly in Michigan). Ali's family settled in Minneapolis, Minnesota, in 1992. He attended Robbinsdale Cooper High School in New Hope, Minnesota. He has a son, Faheem, from his first marriage, and remarried in 2008. On the song "Real As Can Be" off his [EP] "Truth is Here" he says he also has a daughter on the way. According to the song "Fresh Air" on his September 2009 album Us, he goes on to say "Just got married last year/ treated so good that it ain't even fair/ already gotta boy now the baby girl's here/ Bought us a house like The Berenstein Bears." He has family in the Minneapolis area. Brother Ali takes family very seriously and sees it as a major part of life.

Ali was born with the rare genetic condition of albinism, a disorder characterized by a lack of pigment in skin, eyes, and hair. Brother Ali often makes fun of the media's constant urge to mention his condition in the first lines of their reviews or newspaper articles. He is also legally blind which is caused by his albinism.
