Long Form pointed me to a great 1993 New Republic article by Alexander Star about Philip K. Dick. An excerpt:

A heavy man with an absent smile and an intent gaze, Philip Dick typed 120 words a minute even when he wasn’t on speed, drank prodigious quantities of scotch and completed five marriages and over fifty novels before the pills and the liquor conspired to kill him at 54. His busy life has been ably narrated by Lawrence Sutin in his biography, Divine Invasions, which appeared a few years ago. Born in 1928, Dick witnessed the Depression from inside a broken home. His father, an employee of the Department of Agriculture, left the family in 1931 and went on to host a radio show in Los Angeles called This is Your Government. Dick grew up with his mother on the fringes of Berkeley’s fledgling bohemia. A troubled student, he was often “hypochondriacal about his mental condition,” as one of his wives later put it. And like many troubled boys of the time, he became a voracious reader of the science fiction pulp magazines that were then at their peak. In Confessions of a Crap Artist, a novel written in 1959, he wryly portrayed himself as an awkward kid spouting oddball ideas from Popular Mechanics and adventure stores: “Even to look at me you’d recognize that my main energies are in the mind.”•
