This view is supported by an (as yet unpublished) detailed investigation of Einstein’s theory of distant parallelism by T. Sauer which I received 6 month after after having submitted this review [288]. Sauer uses unpublished correspondence in the Einstein Papers Archive, and points to “some historical and systematic similarities between the Fernparallelismus episode and the Entwurf theory, i.e., the precurser theory of general relativity theory pursued by Einstein in the years 1912-1915.”
