The article was inspired by a group photo of twelve young Polish scientists, taken in the summer of 1907 in Göttingen. Some of the men portrayed in it – then still scholarship holders and students – gained worldwide fame a few years later, and almost all of them became famous scientists in pre-World War II Poland. The original of the photo, ref. no. ZF.263, was stored in the Archives of Polish Mathematicians in Sopot and is currently in the Central Mathematical Library of the Institute of Mathematics of the Polish Academy of Sciences (CBM IMPAN) in Warsaw. This photograph is a valuable memento for the history of Polish science. The article aims to reestablish the actual faces and names connection of the people in the photo since even renowned experts in photography had problems with their proper identification. The text gives examples of publications with a reproduction of the photo ZF.263 (or part of it) where some people are identified incorrectly.
