Why more books on Albert Einstein? Two years ago we marked the Year of Physics, celebrating the centenary of his great 1905 papers, including those on special relativity and the particle theory of light. There is already a definitive scientific biography, published by Abraham Pais in 1982. That Einstein had an interesting personal life, with many entanglements with women and at least one extramarital child, has not been news since Roger Highfield and Paul Carter's The Private Lives of Albert Einstein and Dennis Overbye's Einstein in Love, published in 1994 and 2000, respectively. His private letters continue to come to light, but do they really add anything to the portrait of Einstein's character drawn so perceptively by Overbye?
