Now a major motion picture, the New York Times-bestselling, first-and only-definitive authorized biography of Neil Armstrong, one of America's most celebrated yet enigmatic heroes.

Now a major film starring Ryan Gosling, Claire Foy and Kyle Chandler, directed by Oscar-winner Damien Chazelle, First Man by James Hansen offers the only authorized glimpse into the life of America’s most famous astronaut, Neil Armstrong – the man whose “one small step” changed history.

In First Man, Hansen explores the life of Neil Armstrong. Based on over 50 hours of interviews with the intensely private Armstrong, who also gave Hansen exclusive access to private documents and family sources, this “magnificent panorama of the second half of the American twentieth century” (Publishers Weekly, Starred Review) is an unparalleled biography of an American icon.

When Apollo 11 touched down on the moon’s surface in 1969, the first man on the moon became a legend. Hansen vividly recreates Armstrong's career in flying, from his seventy-eight combat missions as a naval aviator flying over North Korea to his formative transatmospheric flights in the rocket-powered X-15 to his piloting Gemini VIII to the first-ever docking in space. For a pilot who cared more about flying to the Moon than he did about walking on it, Hansen asserts, Armstrong's storied vocation exacted a dear personal toll, paid in kind by his wife and children. In the years since the Moon landing, rumors swirled around Armstrong concerning his dreams of space travel, his religious beliefs, and his private life.

This book reveals the man behind the myth. In a penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and as an individual. In First Man, the personal, technological, epic, and iconic blend to form the portrait of a great but reluctant hero who will forever be known as history's most famous space traveler.

'Jim Hansen has captured the essence of Neil Armstrong, not only as the first man on the Moon, but also as an outstanding aviator and astronaut. I was there for Neil’s other major "space step"—he recovered Gemini 8 from the ultimate end game with aggressive action, cool skill and creative judgement seldom performed in any aviation or space endeavor. Just 16 days after the deaths of the Gemini 9 crew, he probably saved the Moon. Jim Hansen has written an exceptional and accurate account of a unique period in aerospace history and the adventures of Neil Armstrong.'
