EINSTEIN, Albert. Four autograph letters signed ('Papa') to his son Eduard ('Lieber Tetel'), Caputh and n.p., n.d., 2 pages, 8vo, and 3 pages, 4to (letter from Caputh, n.d., has short tear to left margin at centrefold, touching 3 words, and 2 small rust stains).
Einstein grasps at solutions to the Unified Field Theory. 'I am in a very good mood, because the new theory is making such good progress'; in another letter, 'My theory has grown wonderfully. I'm the only scientist to have been enthusiastic about it up to now, but I'm completely on fire with it'; again 'the work with Dr Mayer is proceeding beautifully. I've never had such a gripping problem (So ein fesselndes Problem hab ich noch nie gehabt). I believe we will soon be able to grasp why electrical particles all have the same charge. It is like a simple bonding of space (eine einfache Verknotung des Raumes ). It is almost too beautiful to be true'. The letters discuss a variety of other subjects, including a detailed question on physiology - 'I find Anatomy and Physiology interesting, but depressing in that they take no account of deeper problems'; the aphorisms which Eduard has been producing, which he finds 'somewhat too clever, not natural or original enough. But you have a very demanding father'; and some books which Einstein has sent - he thoroughly recommends a work by G.B. Shaw. (4)
