William Woolfolk was one of the best writers in the Golden Age of Comics. He worked at various times on all the major characters but his most notable work was on Blackhawk, Plastic Man and Captain Marvel. He eventually left comics and began writing novels and TV shows, including one of the best programs ever produced, The Defenders starring E.G. Marshall. Sure wish TV Land or some other cable channel would start running those.
Here's a link to a too-brief newspaper obit about Mr. Woolfolk. And here's a link to his website, where you can learn more about this extraordinary talent. I had the honor of meeting him at last year's Comic-Con International in San Diego and having him on our Golden Age Panel and he struck me as a charming man, a dedicated writer and someone I wished I'd gotten to know better.
