5. Einstein, Albert. 1956. The meaning of relativity. Fifth Edition. Princeton University Press. This book contains the four lectures delivered at Princeton University in 1921 (pp. 1–108). Translated by Edwin P. Adams. An Appendix was added to the second edition of 1945 (pp. 109–132). Translated by Ernst G. Straus. For the third edition in 1950 another Appendix II was added, which was revised for the fourth edition (1953), and for the fifth edition Einstein completely revised this Appendix in December 1954, about four months before he died. This last version of Appendix II he titled: “Relativistic Theory of the Non-Symmetric Field” (pp. 133–166). Translated by Sonja Bargmann. This last paper was written with Bruria Kaufman, an Israeli physicist and his last collaborator.
