Josh Mensch is a New York Times bestselling author and documentary television producer with a focus on American history and culture. He is the co-author of the nonfiction history book The First Conspiracy: The Secret Plot to Kill George Washington (Flatiron Books), written with award-winning novelist Brad Meltzer. In January 2019, The First Conspiracy debuted at #3 on the New York Times bestseller list for nonfiction.

In addition to writing books, Josh has been a documentary television showrunner, writer, director, and producer. He has created a wide variety of historical, cultural, and journalistic programming for the most prominent non-fiction networks, including the History Channel, PBS, National Geographic, Discovery and others.

Remarkably, two television stories that Josh wrote and directed led to the recovery of significant artifacts from American history: the iconic flag raised by firefighters at Ground Zero on 9/11 (as featured in Brad Meltzer’s Lost History, for the History Channel), and the electric guitar played by Bob Dylan when he famously “plugged in” at the Newport Folk Festival in 1965 (as featured in History Detectives, on PBS). Also in the realm of American history and politics, Josh has written and produced stories about subjects ranging from World War II battles, to Thomas Jefferson’s slaves, to the Hatfields & McCoys, to the early days of jazz, to the build-up to the Iraq War, to the history of superheroes.

Josh’s credits as a show runner, writer, or producer include: Superheroes Decoded (History Channel), Generation X (Nat Geo), Brad Meltzer’s Lost History (H2/History Channel), Frontline (PBS), History Detectives (PBS), Border Wars (Nat Geo), True Life (MTV), and others. In the course of his projects, Josh has conducted interviews with many famous and/or fascinating figures including senators, actors, film directors, historians, political activists, fashion designers and the occasional astrophysicist.

Josh is a graduate of Princeton University and the Columbia University Graduate School of Journalism. He lives in Brooklyn, NY with his filmmaker wife and their two children.
