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, odd history and unorthodox messages from God, Hartzman is also a Weird News blogger for The Huffington Post (and formerly AOLnews.com) and writes for Bizarre magazine. He is well-known in quirkier circles as the founder, writer, and publisher of Backwash zine -- an award-winning humor magazine that has been exhibited in New York's New Museum for Contemporary Art. 

When not writing about life's oddities, Hartzman writes about various goods and services in the advertising industry.
