Born in 1905 in the city of South Bend (Indiana, USA) within a family of free thinkers, the life of this self-taught writer has taken, with the distance, a bridge: a lucid and solid link between two outstanding moments of the twentieth century: the social convulsions of the beginning of the century and the youth rebellion of the sixties. During the thirties and forties, Rexroth played a very active role within many libertarian groups in defense of civil rights and against war (he declared himself a conscientious objector during World War II), and was at the same time the principal mentor of the cultural and literary ferment that will lead to the so-called «San Francisco Renaissance» after the war. From the fifties he wrote poems, plays, essays and articles of social criticism, translated poetry from seven languages, presented reviews of books and programs on the independent radio KPFA and organized poetry readings accompanied by jazz for the first time. He died in Montecito (California) in 1982. Although Kenneth Rexroth is known among readers in Spanish mainly for his poetic work, his versions of oriental poets and his relationship with the Beat generation, his essays are unmatched. Good sample of it they are Disconnection and other tests (Pepitas, 2009) and this dazzling approach of the classic texts. Soon, will appear in Pumpkin Pepitas his celebrated autobiography: An Autobiographical Novel, with translation by Carlos Manzano.
