This picture is originally shown in „Abhandlungen aus dem Mathematischen Institut der Universität Hamburg“, Band 6 (1928), on an unnumbered page, before page 273 (which starts Radon’s article). The page shows only Radon’s signature in addition to the picture, with no mention of the photographer.

The picture has been reprinted in “Gesammelte Abhandlungen von Johann Radon, herausgegeben von der Österr. Akad. d. Wiss. Unter Mitw. von Peter Manfred Gruber – Wien: Österr. Akad. d. Wiss.; Basel; Boston: Birkhäuser, Band 2 (1987), ISBN 3-7001-1170-3“, with the remark: “Veröffentlicht mit freundlicher Genehmigung des Verlages B.G. Teubner, Stuttgart“.

On January 15, 2008, angelika.bolisega@gwv-fachverlage.de (Teubner Verlag) informed me that the original publisher, B.G. Teubner, has no rights on this picture.

The picture does not appear anywhere except in these two places. It does not appear in the Mathematics Genealogy Project, nor does it appear in the MacTutor History of Mathematics Archive, nor in the book “75 Years of Radon Transform, edited by S. Gindikin and P. Michor, International Press Inc., Boston (1994), ISBN 1-57146-008-X”. Dr. Brigitte Bukovics, Johann Radon’s daughter, has told me on 15 Nov. 2010 that she has not seen the picture anywhere except in these two places and that she has not seen it otherwise in the mathematics book at her disposal.

It may therefore be safely assumed that the photographer is unknown, so that the license tag below applies.

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.
