How Samuel R. Delany Reimagined Sci-Fi

Last September, while working at his desk in Philadelphia, Samuel R. Delany experienced a mysterious episode that he calls “the big drop.” His vision faded for about three minutes, and he felt his body plunge, as if the floor had fallen away. When he came to, everything looked different, though he couldn’t say exactly how. Delany, who is eighty-one, began to suspect that he’d suffered a mini-stroke. His daughter, Iva, an emergency-room physician, persuaded him to go to the hospital, but the MRI scans were inconclusive. The only evidence of a neurological event was a test result indicating that he had lost fifteen per cent of his capacity to form new memories—and a realization, in the following weeks, that he was unable to finish his novel in progress, “This Short Day of Frost and Sun.” After publishing more than forty books in half a century, the interruption was, he told me, both “a loss and a relief.”
