AJ Jacobs is the editor at large at Esquire magazine and author of three New York Times bestsellers.

In 2004, Simon & Schuster published The Know-It-All. It subsequently spent eight weeks on the New York Times paperback bestseller list. It was praised by Time magazine, Newsweek, Vanity Fair, USA Today, Janet Maslin in the New York Times and AJ's uncle Henry on Amazon.com.

In 2007, The Year of Living Biblically was released. It has spent three months on the NYT bestseller list, and was praised by Publishers Weekly, Kirkus Reviews, The New York Times Book Review, the Los Angeles Times, USA Today and others. It appeared on the cover of the evangelical magazine Relevant, but was also featured in Penthouse. (Jacobs is proud to be a uniter, not a divider).

He has appeared on Oprah, The Today Show, Good Morning America and Late Night with Conan O'Brien (though Conan did decline Jacobs' offer to bring the remnants of his shaved beard in a plastic bag).

The Year of Living Biblically is currently being developed by Paramount Pictures, and My Outsourced Life is being developed at Universal Pictures.

He's now working on a book called The Healthiest Human Being in the World. It continues Jacobs' experiential journalism series as he tries to perfect his physical condition while simultaneously dissecting the meaning of the word "healthiest."

Jacobs grew up in New York City. His father is a lawyer who holds the world record for the most footnotes in a law review article (4,824). His wife works for a highbrow scavenger hunt called Watson Adventures. He lives in New York with his family.
