Miltonic echoes in the life of Aldous Huxley:

Just how much Huxley was able to see is uncertain, although his eyes were obviously compromised, forcing him to compensate in creative ways. Julian Huxley thought that his brother developed a Herculean memory so he could better retain what he labored so hard to read. “With his one good eye, he managed to skim through learned journals, popular articles and books of every kind,” Julian recalled. “He was apparently able to take them in at a glance, and what is more, to remember their essential content. His intellectual memory was phenomenal, doubtless trained by a tenacious will to surmount the original horror of threatened blindness.”
