[The founding of the 'Vereeniging Nederlandsch Tijdschrift voor Geneeskunde' [Society of the Dutch Journal of Medicine] on 28 September 1856].

On Sunday the 28th of September 1856, 150 years ago this year, a meeting was held in Amsterdam at which the 'Nederlandsch Tijdschrift voor Geneeskunde' [Dutch Journal of Medicine] was founded. There are strikingly few sources of information on this happening. The 150th volume of the Journal is appearing this year. In view of the coming anniversary, some old documents that had been laid aside at the time of the move from the Jan Luykenstraat to the Johannes Vermeerstraat in 1992 were re-examined. In a bundle of bound meeting reports from the early years, hidden in a folder inserted into the front cover, we found a printed 'Provisional rules and regulations'; the founding date of 28 September is given in these bylaws. These 'Provisional rules and regulations' also contain some handwritten remarks in the handwriting of J. Zeeman, the Chief Editor during the period 1867-1883. For example, he crossed out the provision that the Journal would be published 'at the expense of the editors' and changed this to 'by a society of editors'. This document provides insight into the introduction of the Society of Editors that still publishes the Journal to this day.
