The novelist and poet Jack Kerouac died in 1969, a chronic alcoholic, at the age of 47. He was already something of a legend, not simply for his style of writing but for the style of life that he chronicled. He travelled back and forth across America, and his most famous novel, 'On the Road', became the bible for what he called 'the Beat Generation'.
