In 2002, Bill Zehme landed one of the most coveted assignments for a magazine writer: an interview with Johnny Carson--the only one he'd granted since retiring from hosting The Tonight Show a decade earlier. Zehme was tapped for the Esquire feature story thanks to his years of legendary celebrity profiles, and the resulting piece portrayed Carson as more human being than American TV icon. Following Carson's passing in 2005, Zehme embarked on an exhaustive nearly decade-long research journey, interviewing dozens of Carson's colleagues and friends to craft this "immensely informative and insightful" (The Minnesota Star Tribune) biography, although his efforts were halted by a cancer diagnosis. When he died in 2023 his obituaries mentioned the Carson book, with New York Times comedy critic Jason Zinoman calling it "one of the great unfinished biographies."

Yet the hundreds of pages Zehme managed to complete are astounding both for the caliber of their writing and how they illuminate one of the most legendary talk show hosts of all time: A man who brought so much joy and laughter to so many millions, but was himself exceedingly shy and private. Zehme traces Carson's rise from a magic-obsessed Nebraska boy to Navy ensign in World War II to a burgeoning radio and TV personality to, eventually, host of The Tonight Show--which he transformed, along with the entirety of American popular culture, over the next three decades. Without Carson, there would be no late-night television as we know it. On a much more intimate level, Zehme also captures the turmoil and anguish that accompanied the success: four marriages, troubles with alcohol, and the devastating loss of a child.

In one passage, Zehme notes that when asked by an interview in the mid-'80s for the secret to his success, Carson replied simply, "Be yourself and tell the truth." Completed with the help from journalist and Zehme's former research assistant Mike Thomas, Carson the Magnificent offers just that: an honest assessment of who Johnny Carson really was.
