George L. Jackson

George Lester Jackson (1941–1971) was an American author, prisoner, and revolutionary who became a key figure in the Black Power movement while incarcerated.[1] Convicted in 1960 of armed robbery for stealing $70–$71 from a gas station, he received an indeterminate sentence of one year to life and spent over a decade in California prisons, including seven years in solitary confinement, where he self-educated in Marxist thought and co-founded the Black Guerrilla Family.[1][2] He gained international fame with his 1970 book *Soledad Brother*, a collection of prison letters blending autobiography and political manifesto, and was killed by guards at San Quentin in 1971 amid disputed circumstances.[1][3]
