Surprising Facts about 10 Bestselling Authors (Courtesy of Mental Floss Magazine)

1. Dan Brown didn’t get his start as a writer. Oh, no. Before he penned thrillers like The Da Vinci Code, Brown worked as a pop singer and songwriter. His second solo album, Angels & Demons, even shared its title with one of his literary juggernauts.

2. Former lawyer and politician John Grisham may not need to practice law now that he’s moved 250 million copies of his books, but he did head to court on one special occasion after his literary success. In 1996 Grisham returned to the courtroom to represent the family of a railroad brakeman who was killed on the job. Apparently Grisham still had his chops; he won the case (and over $650,000) for the family.

3. Nora Roberts has been a staple on the New York Times Bestseller List for years, but it wasn’t easy for her to get her foot in the door. According to Roberts, when she was submitting her manuscripts to romance giant Harlequin, the publisher sent her a note rejecting her work because they “already had their American writer.”

4. Danielle Steel’s life sounds surprisingly like something from a Danielle Steel novel. The author has been married five times, and there have been some real winners in the bunch. According to the San Francisco Chronicle, husband number two was a bank robber who was convicted of raping a woman while he was married to Steel, and the third Mr. Steel was a heroin-addicted burglar.

5. The late Sidney Sheldon wrote a whole raft of bestsellers even though he didn’t start writing novels until after he turned 50. Sheldon kept himself pretty busy before his career took off, though, by creating TV hits like The Patty Duke Show and I Dream of Jeannie. Sheldon also won an Oscar for Best Original Screenplay for penning The Bachelor and the Bobby-Soxer.

6. Bestselling thriller author John Sandford’s work may not be considered high art, but he’s got something a number of his more ambitious literary colleagues would kill for: a Pulitzer Prize. Sandford, whose real name is John Camp, picked up a Pulitzer for Non-Deadline Feature Writing in 1986 for a series of articles in the Saint Paul Pioneer Press that chronicled a year in the life of a Minnesota farming family.

7. Having Stephen King as your dad has its perks. In the late 80s, King’s son Owen was just as obsessed with G.I. Joe as any other boy. Owen, though, got a little shout-out most of us didn’t receive. When Hasbro introduced the new G.I. Joe Sneak Peek in 1987, the character’s promotional materials stated that his real name was “Owen S. King,” a gesture that may have stemmed from Owen’s dad helping to create another G.I. Joe character.

8. Thriller author Clive Cussler often writes about searches for underwater shipwrecks, and it’s a topic he knows a thing or two about. Cussler founded the non-profit National Underwater & Marine Agency, and together with his NUMA volunteers has located more than 60 historically significant shipwrecks.

9. Jodi Picoult has enjoyed quite a bit of success as a novelist, but she’s also dabbled in comics. In 2007, she wrote a five-issue arc for Wonder Woman.

10. Nicholas Sparks’ works like The Notebook fly off of store shelves, but they might not move as quickly as their author. Sparks not only attended Notre Dame on a track scholarship, he also helped set a still-standing school record in the 4 x 800m relay.
