Second only to Upton Sinclair among prolific and famous California authors of the early twentieth century, Jack London achieved huge literary success at a young age despite modest origins. I have now read two of the autobiographical novels set partly in California, The Sea-Wolf and Martin Eden and am engaged in a 2017 biography of London by Earle Labor.
London’s natal Sun in Capricorn is one degree from that of his father of record, astrological author W. H. Chaney. The biographical record is unclear as to whether Chaney was his biological father.
