Translation of Einstein's Attempt of a Unified Field Theory with   Teleparallelism
  We present the first English translation of Einstein's original papers related to the teleparallel ('absolute parallelism', 'distant parallelism' and the German 'Fernparallelismus' are synonyms) attempt of an unified field theory of gravitation and electromagnetism. Our collection contains the summarizing paper in Math. Annal. 102 (1930) pp. 685-697 and 2 reports published in 'Sitzungsberichte der Preussischen Akademie der Wissenschaften' on June 7th, 1928 (pp. 217-221), June 14th, 1928 (pp. 224-227) and a precursor report (July 9th, 1925 pp. 414-419). To ease understanding, literature on tensor analysis is quoted in the footnotes.
