In his knowledge it is not in the archive of the Zeiss company.

Beck suggested to make the Diarium “Public Domain” after all. Some years ago Hans Beck and Stephani talked about the Diarium and the Excel version of it. Some years later Walter Stephani took the trouble to transfer this long list into an Excel spreadsheet, also to be able to search for different aspects in the list. Beck mentioned that he had some documents that could be interesting and useful, and he gave to Mr. Beck celebrated his 90th birthday a few weeks ago). During a visit to Jena around the year 2000 he met the former head of the Zeiss Astro Department, Hans Beck, who was already retired at that time (by the way, Mr. Stephani writes that in his files he had a PDF-copy of the Diarium since many years.
