Jack Kerouac was born in 1922 in Lowell, Massachusetts, and rose to fame with his landmark novel On the Road, which captured the raw, kinetic energy of postwar youth searching for meaning outside conventional American life. Blending stream-of-consciousness prose, Buddhism, jazz, and autobiographical storytelling, Kerouac helped shape an entire countercultural movement that challenged conformity and celebrated experience, travel, and inner awakening. His work deeply influenced generations of writers, musicians, and artists, making him one of the most important literary figures of the 20th century.
