by Rudolf Kayser
Born in Parchim on November 28, 1889, Rudolf Kayser studied literature and earned a doctorate before beginning his career as a teacher and lecturer. He made his literary debut during the late 1910s and soon joined the S. Fischer publishing house, where he became closely involved with German literary life.
Kayser went on to serve as editor in chief of Die Neue Rundschau, an influential literary journal. He was known as a literary historian, critic, and essayist, and his work connected scholarship with a lively interest in contemporary culture.
In 1933, after the Nazi rise to power, he left Germany, later settling in New York. Kayser was married to Ilse, Albert Einstein's stepdaughter, and wrote a biographical portrait of Einstein under the pseudonym Anton Reiser. He died in New York City on February 5, 1964.
