Woolfolk worked in the comic book business, starting with MLJ Magazines, from 1941 through 1954, with time out for military service. He rose in the business to become one of the highly paid writers of comic books, earning $300 a week, ten times the average salary. He toiled for several companies, including Detective Comics ; Fawcett Comics ; Quality Comics ; Police Comics ; and Timely Comics, the precursor to Marvel Comics. He claimed he created Captain Marvel's "Holy Moley!" catchphrase. He also worked for Archie Comics, National Comics and Orbit Publications. After military service in the Army during World War II, he became a freelance magazine writer, eventually joining the staff of Shock Illustrated. He also created O.W. Comics and the astronautics magazine Space World. He became famed as "The Shakespeare of Comics" during the Golden Age of Comics. After a decade of working at Fawcett, Detective Comics editor Mort Weisinger hired Woolfolk for Superman, a marketplace rival of Captain Marvel, one of the titles Woolfolk worked on. At the same time of his hiring, he was also working for Orbit and Timely and freelancing articles and stories to mainstream magazines. He accepted the offer to gain security. However, he clashed with Weisinger and continued to freelance with a wide variety of publishers. His days as a top writer in comics, though, were coming to an end. At the request of Kable News, he became a periodical publisher in 1955, launching the monthly gossip magazine Inside Story as a rival to Confidential. It eventually became the second best-selling scandal sheet in the trade. He eventually left publishing for novel writing and to work in television. Woolworth told the anthology Contemporary Authors:
"Writing during the so-called Golden Age of comics, I soon became the best paid and most sought-after writer in the field. I wrote for all the characters now so nostalgically remembered: Captain Marvel, Superman, Batman, Captain Midnight, Blackhawk, Plastic Man and many others. This work paid so well, was so easy to do, and so much fun, that my versatility might have come to an end forever. But the Golden Age passed, and I moved on."
Woolfolk became a TV screenwriter, primarily working on the courtroom drama The Defenders, where he also was a script editor. A 1965 episode he wrote, "All the Silent Voices", was one of the first to deal with birth control. In 1964, he was nominated for Writers Guild of America award in 1964 for Episodic TV Drama for The Defenders episode "A Book for Burning". He also worked on the crime dramaArrest and Trial, a show that was a forerunner of Law & Order. In the first half of each 90-minute episode, a detective investigated a crime, while in the second half, a member of the District Attorney's office tried the case. The series lasted only one season in 1963-64.
Novelist
Though his first novel, The Naked Hunter, was published in 1953, it was not until 1962 that he published his first hardcover book, when Doubleday issued My Name is Morgan, which was based on the life of Mike Todd. Most of his novels dealt with characters based on actual people, romans à clef limning the lives of celebrities, including , a bestseller evocative of the life of Todd's former wife Elizabeth Taylor and her fifth husband Richard Burton; , based on the construction of the Seagram Building, featured characters based on the Modernist architect William Lescaze and the real estate developerWilliam Zeckendorf; and Maggie, based on the relationship of newspaper publisherWilliam Randolph Hearst and his movie star mistress Marion Davies. Woolfolk wrote TV tie-ins based on the Batman TV series: Batman vs. Three Villains of Doom and Batman vs. the Fearsome Foursome. He also wrote nonfiction: The Great American Birth Rite, co-authored with his wife Joanna Martine Woolfolk, about child raising; and Daddy's Little Girl: The Unspoken Bargain Between Fathers and Their Daughters, co-written with his daughter, the novelist Donna Woolfolk Cross Woolfolk died of congestive heart failure in Syracuse, New York, in 2003. At the time of his death, his novels had sold over six million copies, and eight had been selected by the Book of the Month Club. In his interview with Contemporary Authors, Woolworth summed up his writing career:
No literary monuments have ever been erected that proclaim: 'He was versatile'. No one looks forward to a new book by William Woolfolk because no one, including the author, knows what it will be.
He claimed that his comic books work outshone his other literary production.
