Geronimo (1834-1909) was an Indian chief, head of the Chiricahua Apaches, whom he led in revolt between 1881-86, terrorizing ranchers in New Mexico and Arizona. He surrendered to General Crook in 1882, but escaped to the Mexican mountains, where he was again captured. He and his followers were imprisoned in 1886 at Ft. Pickens, Florida, but were released two years later and sent to Oklahoma reservation.
