We are often amazed by the wide-eyed innocence and boundless curiosity of children and the questions they ask. And letters to and from children are always appealing, especially so when they are written to someone famous. In "Dear Professor Einstein", Alice Calaprice has gathered a delightful and charming collection of more than sixty letters, most never published before, from children to perhaps the greatest scientist of all time. Obviously, Einstein could not respond to every letter written to him, but the responses he did find the time to write reveal the intimate human side of the great public persona, a man who, though he spent his days contemplating mathematics and physics, was very fond of children and enjoyed being in their company.Whether the children wrote to Einstein for class projects, out of curiosity, or because of prodding from a parent, their letters are amusing, touching, and sometimes quite precocious. Enhancing this correspondence are numerous splendid photographs showing Einstein amid children, wearing an Indian head-dress, carrying a puppet of himself, and donning fuzzy slippers, among many other wonderful pictures, many published for the first time in this book. Complete with a foreword by Einstein's granddaughter Evelyn, a biography and chronology of Einstein's life, and an essay by Einstein scholar Robert Schulmann on the great scientist's educational philosophy, this wonderful compilation will be welcomed by teachers, parents, and all the young, budding scientists in their lives.
