Portrait of Johann Radon about 1920

Komentář k Licence:

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.
