Prince Harry may have been all over the press for his highly anticipated memoir, Spare, which will be released on Tuesday. But Harry didn't write the 416-page book all by himself: he enlisted the help of ghostwriter J.R. Mohlinger. Who is Mohlinger? For starters, he is a best-selling author and Pulitzer Prize winner, People reports.

Many people are unaware of the ghostwriting process, and since "Spare" is written in the first person, they may forget that ghostwriting even took place. The New York Times (and via People) states that "ghostwriters use someone else's voice - often someone else's highly recognizable voice - to construct a book with form, texture, narrative arc, and memorable characters, without leaving fingerprints."

This is not Moehlinger's first time ghostwriting a celebrity's book. In addition to ghostwriting memoirs for tennis pro Andre Agassi (2009's Open) and Nike founder Phil Knight (2016's Shoe Dog), Mohlinger has also written his own memoir, The Tender Bar. The Tender Bar "touches on the childhood challenges Moehringer has faced in the past - his relationship with his mother, growing up without a father, and his struggles with alcohol," People reports. The Tender Bar was adapted into a 2021 film directed by George Clooney and starring Ben Affleck.

Moehringer was born in New York City, raised by a single mother in Manhasset, and moved to Scottsdale, Arizona, where he attended high school, People reported. he received a bachelor's degree from Yale University in 1986 and began his career in journalism as a copy boy at The New York Times He began his journalism career as a copyboy at The New York Times. He then wrote for the Rocky Mountain News in Colorado (where he wrote "Tender Bar" in 2005) and other publications before joining the Los Angeles Times as a national correspondent. While working for this publication, he was a Pulitzer Prize finalist in 1998 for his article "Resurrecting the Champ" and again in 2000 for "Crossing Over," which won journalism's highest award in the feature writing category.

He is also a novelist, and in 2012 he wrote "Sutton," a mystery biography of bank robber Willie Sutton, under his own name.

According to a 2012 interview with NPR, Mohlinger has a specific process in his ghostwriting work. He said, "You're thinking in the third person, but you're writing in the first person, so the processes are like mirror images of each other, but very similar."

"Spare" will finally be released on Tuesday.
