(Com reutilitzar aquest fitxer)

This photograph was taken in 1912 for postcards of faculty members at the University of Göttingen which were sold to students at the time (see "Hilbert", Constance Reid, Springer 1970). It was therefore published before 1923. Since it is not written in a foreign language, it is public domain in the US.

It is likely that the original copyright holder was the photographer, and it is reasonable to assume that someone of professional age in 1912 died before 1964. This does not affect the copyright status in the US, but may mean that the image is also in the public domain in countries where the copyright term is life of author plus 50 years.

To use this template, the image must meet both of the following two conditions:
  1. published over 70 years ago, and
  2. the original author's actual identity was not publicly disclosed in connection with this image within 70 years following its publication.

Images that lack either of these two conditions should not use this template.

Reasonable evidence must be presented that the author's name (e.g., the original photographer, portrait painter) was not published with a claim of copyright in conjunction with the image within 70 years of its original publication. Works which had not entered Public Domain in their country in 1996 that were uploaded before 1 March 2012 should be marked additionally with {{Not-PD-US-URAA}}.

Note: In some countries anonymous works are copyrighted until 70 years after the death of the author if the author's identity became public in any way during the original term. In Germany this applies to certain works published before July 1, 1995; see Übergangsrecht.
