According to ABCnews.com, Marc Hartzman is "one of America's leading connoisseurs of the bizarre." His passion for the unusual began at an early age, influenced by Ripley's Believe It Or Not and the annual Guinness Books.
In addition to his books about weird things on eBay, sideshow performers, Cromwell's embalmed head, and unorthodox messages from God, Hartzman was a frequent contributor to Bizarre magazine and currently runs WeirdHistorian.com. He’s discussed oddities on CNN, MSNBC, and the Travel Channel’s Mysteries at the Museum.
When he's not writing about life's more unusual side, Hartzman earns a living as an award-winning advertising creative director.
