Jean-Louis "Jack" Kérouac (/ˈkɛruːæk/ or /ˈkɛrɵæk/; March 12, 1922 – October 21, 1969) was an American novelist and poet. He is considered a literary iconoclast and, alongside William S. Burroughs and Allen Ginsberg, a pioneer of the Beat Generation.[2] Kerouac is recognized for his method of spontaneous prose. Thematically, his work covers topics such as Catholic spirituality, jazz, promiscuity, Buddhism, drugs, poverty, and travel. He became an underground celebrity and, with other beats, a progenitor of the hippie movement, although he remained antagonistic toward some of its politically radical elements.

In 1969, at age 47, Kerouac died from internal bleeding due to long-term alcohol abuse. Since his death Kerouac's literary prestige has grown and several previously unseen works have been published. All of his books are in print today, among them: The Town and the City, On the Road, Doctor Sax, The Dharma Bums, Mexico City Blues, The Subterraneans, Desolation Angels, Visions of Cody, The Sea is My Brother, and Big Sur.

Born Jean-Louis Kerouac, Kerouac is the most famous native son of Lowell, Massachusetts. His parents had immigrated as very young children from the Province of Quebec, Canada, and Kerouac spoke a local French Canadian-American dialect before he spoke English. He was a football star at Lowell High School and upon graduation in 1939 was awarded a scholarship to Columbia University. However, after an injury sidelined him on the football team, Kerouac grew unhappy with Columbia and dropped out of school. During this period in New York City, Kerouac became friends with the poet Allen Ginsberg and the novelist William S. Burroughs, as well as Herbert Huncke and others who would be associated with the “Beat Generation.”

From Biography.com

Famed writer Jack Kerouac was born Jean-Louis Lebris de Kerouac on March 12, 1922, in Lowell, Massachusetts. A thriving mill town in the mid-19th century, Lowell had become, by the time of Jack Kerouac's birth, a down-and-out burg where unemployment and heavy drinking prevailed. Kerouac's parents, Leo and Gabrielle, were immigrants from Quebec, Canada; Kerouac learned to speak French at home before he learned English at school. Leo Kerouac owned his own print shop, Spotlight Print, in downtown Lowell, and Gabrielle Kerouac, known to her children as Memere, was a homemaker. Kerouac later described the family's home life: "My father comes home from his printing shop and undoes his tie and removes [his] 1920s vest, and sits himself down at hamburger and boiled potatoes and bread and butter, and with the kiddies and the good wife."
