“The author of this book is one who knows me rather intimately in my endeavor, thoughts, beliefs - in bedroom slippers. I have read it to satisfy, in the main, my own curiosity. What interested me was not a desire to know what I am or look like, but rather another's avowal of what I am. I found the facts of the book duly accurate, and its characterization, throughout, as good as might be expected of one who is perforce himself, and who can no more be another than I can. What has perhaps been overlooked is the irrational, the inconsistent, the droll, even the insane, which nature, inexhaustibly operative, implants in an individual, seemingly for her own amusement. But these things are singled out only in the crucible of one's own mind. This is as it should be. For, otherwise, how could the isolation of distance be approximated?” (Albert Einstein)

This biography was written by Albert Einstein’s close relative, his son-in-law, Rudolf Kayser. It was first published in 1930 under the pseudonym "Anton Reiser" which itself is the title of an important book of the literary history of Germany. This rediscovered work holds many new fascinating facts and personal insights about this beloved character of our time, Albert Einstein, as well as context about his greatest ideas and concepts, including quantum physics, the theory of relativity, space time and the laws of our universe.
