Einstein: His Life and Universe is a non-fiction book authored by American historian and journalist Walter Isaacson. The biographical analysis of Albert Einstein's life and legacy was published by Simon & Schuster in 2007, and it has received a generally positive critical reception from multiple fronts, praise appearing from an official Amazon.com review as well as in publications such as The Guardian and Physics Today.

In broad terms, the book portrays Einstein as an insolent figure who possessed a strong sense of creativity and independence that, had the physicist succeeded in achieving academic employment as a young man, could have gotten quashed due to the atmosphere of the times.

Isaacson had previously written books on the life stories of statesmen Benjamin Franklin and Henry Kissinger. In preparation for the work on Einstein, the author delved into volumes of previously examined writings to and from the physicist. Isaacson additionally collaborated with scientists Murray Gell-Mann, Brian Greene, and Lawrence Krauss to gain knowledge about the underlying background.

Isaacson's biographical analysis of Einstein's life reflects the nature of personal achievement in terms of the importance of inquisitiveness and the willingness to experiment. The physicist's theory of general relativity receives particular emphasis. Broadly speaking, Einstein is viewed as a kind of inherent rebel.

The author describes Einstein's insolent streak and how the sometimes abrasive nature around it cost Einstein much in the short term, though larger society benefited dramatically in the long run. After going through his studies in physics with "a sassy attitude" at the Zurich Polytechnic, Einstein wound up being the only graduate of his year's class not to be offered a job. The author notes Einstein's subsequent trek throughout Europe in search of work and its failure. "I will soon have graced every physicist from the North Sea to the southern tip of Italy with my offer," Einstein is quoted as writing. Rejected by the Swiss army for his misshapen feet and varicose veins, Isaacson details, Einstein finally managed to start a career at the Swiss patent office. Despite the mediocre posting, his independent research into his intellectual passions proved highly influential as Isaacson describes.

The Observer published a supportive review by journalist Robin McKie. He remarked that Isaacson "triumphed over expectation[s]" as well as wrote that the "thorough exploration of" Einstein's life constituted both "a skilful piece of scientific literature and a thumping good read." McKie labelled Einstein's life story as one of the most interesting tales "in modern science" and lauded Isaacson's "first-rate job in telling it."

The official Amazon.com review of the book, written by Anne Bartholomew, praised the author's approach and details, Bartholomew commenting,

"Isaacson... brings Einstein's experience of life, love, and intellectual discovery into brilliant focus. The book is the first biography to tackle Einstein's enormous volume of personal correspondence that heretofore had been sealed from the public, and it's hard to imagine another book that could do such a richly textured and complicated life as Einstein's same thoughtful justice. Isaacson is a master of the form and this latest opus is at once arresting and wonderfully revelatory."
