ABCnews.com has called Marc Hartzman "one of America's leading connoisseurs of the bizarre" and George Noory from Coast to Coast AM said he's "as bizarre as Robert Ripley." Hartzman considers both high compliments since his passion for the unusual started with Ripley's Believe It Or Not and the annual Guinness World Records books during his youth.

In addition to his books about ghosts, Mars, Oliver Cromwell's embalmed head, weird things on eBay, sideshow performers, and unorthodox messages from God, Hartzman has written for Mental Floss, the Huffington Post, AOL Weird News, AllThatsInteresting.com, and Bizarre magazine. He's discussed oddities on CNN, MSNBC, Ripley's Radio, and the Travel Channel's Mysteries at the Museum.

More of his love for the unusual can be found on his site, WeirdHistorian.com. Outside of these projects, Hartzman earns a living as an award-winning advertising creative director.
