Albert Einstein is a bibliography by Anton Reiser, a pseudonym for Rudolf Kayser, the husband of Einstein’s stepdaughter. Kayser, a German literary historian, gives an intimate view of the life of one of the greatest physicists who has ever lived. Einstein describes his familiarity with the author in his introduction of the book, writing, “The author of this book is one that knows me rather intimately in my endeavors, thoughts, beliefs- in bedroom slippers.” The book is divided into six chapters: Childhood and Early Life, Self-Support, Formulation of The Theory of Relativity, War-Time and After, Fame, and Einstein Today. This biography was published in 1930, three short years before Einstein was forced to flee Germany, due to Adolf Hitler’s rise to power and new laws banning Jews from holding official positions. Shortly after fleeing the country, Einstein’s books were targeted in the Nazi book burnings, a 5,000 Reichsmark bounty was put on his head, and the Nazi government pilfered his cottage and sailboat. Rudolf Kayser, the author, was also forced to leave Germany in 1935 because of his Jewish heritage. Albert Einstein was researching at the California Institute of Technology in Pasadena in 1931. He inscribed this copy that same year.. Signed. First Edition. Hard Cover. Very Good.
